In-Mold Electronics (IME): How In-Mold Decorating (IMD) and In-Mold Labeling (IML) are Changing the Game for Designers

In-Mold Electronics (IME), or Smart Structural Surfaces™, promise to be a game-changing technology that will significantly improve process optimization. 

IME provides for a streamlined production process over traditional electronic assembly. Simply put, IME is a three-step process which includes the printing of electronic circuits and graphics, followed by the forming and molding. However, In-Mold Electronics is often confused with related processes, namely In-Mold decorating (IMD) and In-Mold Labels (IML).

What is the Difference Between IML and IMD?

IME’s roots are tied to both IMD and to a lesser degree IML. IME takes the process of printing, forming, and molding to a new level of complexity. Both IMD and IML offer a streamlined process utilizing printing, forming and molding. All three offer an enhancement in the production of parts with complex 3D geometries. 

An In-Mold Decorating or In-Mold labeling process only offers a decorative function. Typical examples of IMD include molded plastic parts, such as mobile phone covers. In-Mold labels can be found in a broad variety of plastic containers and consumer packages, such as for ice cream tubs, shampoo bottles, and many more. 

                    Ice creams tubs IML

In-Mold Electronics specifically describes a more complex process which, like IMD and IML, begins with fundamentally the same three primary processes of printing forming and molding. However, IME is dramatically different in that it marries electronic functionality to the decorative process making the part a functional Human Machine Interface (HMI) for industrial or consumer applications. These parts are referred to at E2IP as Smart Structural Surfaces™. 

Smart Structural Surfaces™: A Step Forward for IME

The IME process begins by printing stretchable conductive inks onto a film to create fully functional electronic circuits. A graphic overlay is printed onto the second film. These graphics align with the electronic circuitry and can include icons for intuitive user interaction as well as to serve the aesthetic design. The films are then thermoformed into the desired 3D shape. Electronic components can be added to the circuits before or after thermoforming. The part can include lights, sound and haptic feedback. The graphic layer and the circuit layer are placed together in the mold cavity of an injection mold. The injection molding embeds all the components creating a single, rigid molded plastic part.

Smart Structural Surfaces™ offer a range of benefits over traditional HMI components, including increased durability, reduced manufacturing costs, and improved design flexibility. By eliminating the need for additional assembly and reducing the number of components needed, Smart Structural Surfaces can significantly reduce production costs and waste.

Everything You Need To Know About Membrane Switches

What are Membrane Switches?

A membrane switch is a user interface device that is made up of several layers and used as a switch to turn a device on or off. Unlike mechanical switches, which are generally constructed with copper and plastics, membrane switches are printed circuits on film.

 

How do Membrane Switches Work?

The design behind most membrane switches is simple: when an operator presses a button, a contact is made activating the circuit. When the operator releases the button the contact ends deactivating the circuit.

 

How are Membrane Switches Made?

The design and manufacturing process behind membrane switches is one e2ip technologies  handles with much care and creativity. Membrane switches are made by printing a carbon or silver ink onto various substrates. A customized graphic overlay is then applied to the film. At e2ip technologies , we offer a wide range of graphic layer material, including polyester, antimicrobial polyester, polycarbonate, blends, and silicone. These pliable, durable materials are where “membrane” switches get their name.

Where are Membrane Switches Used?

Membrane switches are used in a number of applications, including in medical, aerospace, defense, industrial, and transport industries. They are often used for keypads, control panels in aircrafts, touch screen phones, and kidney dialysis machines—just to name a few.

Membrane switches are revered for their durability and flexibility, especially in high or low-temperature environments. They are also known for their reliability and high conductivity.

Types of Membrane Switches

There are two main types of membrane switches, each performing different functions on the circuit board

Tactile. Tactile switches are designed to provide a response when pressed by an actuator or finger. An overlay over the switch has symbols or letters used to designate the function of each switch. Generally, these switches are designed using metal domes. When pressed, the metal dome pushes against a conductive footprint, causing an action to happen.

Non-tactile. This type of switch operates with the same concept as a tactile switch but does not elicit a tactile response. With the bottom of the overlay connecting to a conductive pad, non-tactile switches are self-contained units.

At e2ip technologies, we provide a variety of membrane switches for applications in the medical, aerospace, defense, industrial, and transport industries. Our engineering and design teams are committed to providing you with a durable, reliable, and eco-friendly product, guaranteed to improve efficiency within your business.

From medical devices to factory automation, there are many embedded systems all around us that have changed how we interact with the world. Advanced embedded control, communications and human machine interface (HMI) systems are responsible for delivering responsive and elegant user experiences across a wide range of industries.

In this blog post, we will explore embedded systems in modern technology and the features and functionality required of touchscreen HMI modules to create the next generation of devices, with a look towards the design and engineering challenges that have held back many industry stakeholders.

What are Embedded Systems?

Embedded systems perform specific tasks with larger machines and devices. There are many types of embedded systems, and they can be found everywhere from industrial machines to  medical equipment to aerospace components.

Industrial embedded systems often have an embedded operating system and embedded software to perform specific monitoring and control functions. Similarly, modern medical equipment contains a wide variety of embedded systems for sensors and control mechanisms.

A basic embedded system is a computing system with its own hardware and software that can interact with various input and output devices. Their hardware and software complexities can vary significantly from application to application, ranging from having no user interface (UI) – for example, on devices designed to perform a single task within a mobile embedded system – to complex graphical user interfaces, such as the smart surfaces found in modern aircraft interior controls.

Embedded System Applications

Embedded systems are required in a wide range of industries, including the food & beverage, energy, medical, manufacturing, instrumentation and white goods sectors. Each of these industries has its own unique needs, but all of them require embedded systems that are reliable, efficient and easy to use.

The food & beverage industry requires embedded systems that can withstand harsh environments and provide accurate measurements. Embedded systems in the energy sector must be able to handle large amounts of data and be highly energy efficient. Medical embedded systems need to be small, lightweight and easy to sterilize. And manufacturing embedded systems must be rugged and able to withstand the rigors of the production line.

No matter the industry, embedded systems must be designed with the user, as much as the application, in mind. The best embedded systems are those that are reliable, easy to use and provide a great user experience.

Embedded Systems in Healthcare

Healthcare devices and equipment, such as diagnostic equipment and imaging systems, rely on embedded control systems. Examples of HMIs and embedded systems working in conjunction include digital flow sensors, magnetic resonance imaging machines, patient monitoring systems, and more medical technology.

Furthermore, the growth of the Internet of Things (IoT) presents new opportunities for embedded operating systems in healthcare. For example, future wearables with real-time operating system capabilities may track health data, such as vital signs, and transmit it to healthcare service providers for instantaneous monitoring and diagnosis.

Embedded Systems & Consumer Product Innovation

The world of consumer products has always looked for ways to deliver increased functionality, however, adapting HMI modules to allow for the integration of more advanced assemblies to industry needs and demands has proven to be quite challenging. In order to meet the needs of next-generation products, embedded system design must include elegant human machine interfaces and effective communication technology, especially for the digital data needs of networked embedded systems, and intuitive controls.

Human Machine Interfaces

Human machine interfaces (HMIs) are essential for allowing users to interact with embedded systems. HMIs can take many different forms, including buttons, touchscreens, keyboards and voice-activated controls.

The best HMIs are those that are easy to use and provide a great user experience. When designing an HMI, there are a few key considerations that must be taken into account. First, the HMI must be appropriate for the specific application. For example, a button may be fine for a simple function, but more complex applications call for smarter HMI touch surfaces that are scalable, reusable, connected and secure. Also, the HMI must be durable and able to meet necessary certification standards.

Integrated HMI Modules

 

As the world becomes increasingly connected, the need for advanced HMI designs is also on the rise. These add-on HMI modules allow for the integration of more complex features into your HMI assemblies, such as LCD interface technology, data storage and processing, Wi-Fi, Bluetooth, USB connectivity and more. This way, you can meet the growing connectivity demands of all modern interfaces and smart surfaces.

These modules are fully integrated into existing systems, allowing for deep and complete embedding into the Original Equipment Manufacturer’s (OEM) product. With these modules at your disposal, you’ll be well-equipped to create the next generation of truly connected devices.

For example, the a typical touch screen stack-up includes:

  • Front Bezel
  • Sealing Gasket
  • Resistive Touch Panel
  • Mounting Tape
  • LCD Panel and Chassis
  • Touch Screen Controller
  • Metal Shield
  • Rear Housing Display
Embedded systems provide the computing power needed to make devices and machines smarter and more efficient. As the world becomes increasingly digitized, embedded systems will play an even more important role in our lives.

Communication Technology

One of the most important design aspects of any embedded system is its ability to communicate with other computing systems. Communication can take many different forms, including wired, wireless, Bluetooth and WiFi. In order for an embedded system to function properly, it must be designed to communicate with other systems in a variety of ways.

Whether a small scale embedded system with limited communication needs, or medium-scale embedded systems with more comprehensive communication requirements, effective communication should be a cornerstone of embedded system design.

 

Intuitive Controls

Embedded systems are everywhere, from the thermostat in your home to the navigation system in your car. They are designed to control the environment around them in order to function properly. Controls can take many different forms, including sensors, actuators and embedded controllers.

The best embedded systems are those that are easy to use and provide a great user experience. In order to achieve this, developers must have a strong understanding of how users interact with their systems. They must also be able to design controls that are simple and intuitive to use. When done correctly, embedded systems can greatly improve the quality of our lives by changing the way we interact with our environment.

Engineering and Design Challenges

When designing sophisticated embedded systems, engineers need to consider scalability, reusability, security, and connectivity as often embedded systems must communicate with other systems and output devices.

Creating a system that is easy to use and provides a great user experience is one of the biggest challenges when designing embedded systems. In order to create a system that meets this criteria, engineers must clearly understand how the operator will interact with the system’s human machine interface (HMI).

To create a reliable system, engineers must develop technological specifications that meet exacting electrical, mechanical, and environmental certifications imposed by both governments and industries.

Embedded systems are changing the way we interact with our environment. These systems are becoming more sophisticated, yet easier to use. As embedded systems continue to evolve, engineers will face new challenges in designing these systems. But, with careful planning and innovation, these challenges can be overcome.

Human Machine Interfaces for Military Applications

User Experience in Defense Industry Applications

In order to be prepared for anything, military equipment requires a ruggedized design that can withstand extreme conditions. More importantly, it must have an interface that facilitates the actions required of personnel.

For personnel on the ground, actions and reaction times can literally have life-or-death consequences. Because the success of any military operation relies on the operator’s ability to make correct decisions, human-machine interfaces (HMIs) can play an integral role in enabling them. This is why HMIs for military or defense applications have particularly rigorous demands.

HMIs must meet the highest standards of ruggedization, but also make use of a holistic design that promotes a more efficient and effective user experience. Well-designed HMIs facilitate decision-making and execution by aligning intentions with actions; they provide a frictionless user experience that enables the full range of potential user actions.

Durable Materials & Robust Specifications for High-Performance HMIs

The technologies used in HMIs reflect the fact that it is now necessary to control and monitor complex systems using a single, versatile interface.
