How do printed electronics work

Veres noted that sensors also can be integrated into warehouses and product packaging for supply chain monitoring, which would dramatically reduce the cost over current solutions. Another application is to integrate printed electronics with 3D printing, particularly in areas such antennas. You can have reproducibility and conformity and resistors at interesting geometries.

There are lots of advancements being made. Technology So far, most of the printed electronics have been used in flexible hybrid electronics FHE , typically at large dimensions—something on the order of 1 micron. That is changing rapidly, however. There also are a couple a main methodlogies for putting down inks, which are inkjet or screen.

That could change. And there are limitations at these geometries to the types of structures that can be used. If we have new materials, we can have new unique geometries, so that anywhere you need a structure where the form factor needs to be adjusted, this will work. Getting to that point requires a mix of disciplines, ranging from electrical engineering to material science, chemistry, and nanoparticle research.

Some are sensitive to temperature, while others are sensitive to light. So instead of building up a board, you can add more into every layer. This gives you new design freedom, and it also works for early stage prototyping. This allows us to address cost while creating batteries that are more conformal than coin cells. Challenges ahead While the possible applications are seemingly limitless, printed electronics need to undergo the same kind of rigorous verification, validation and testing as other chips.

This is way different than a finFET, where you have multiple layers but each layer is planar. So there is less correlation with a finFET than you might expect, and you need to know what kind of angle you want to wrap around. That can also change because there is an abundance of different kinds of substrates, and each case will need a different approach. Hopefully we will see some standardize products emerging where the design base is on a common platform.

That would save a lot of cost. That is particularly true for antenna arrays, which could be printed on packages for applications such as 5G. The problem there is an inability to test those devices using standard test equipment, and solutions might apply to printed electronics. You can test them one at a time, or measure at some incident angle. The goal is to measure process defects in RF power, or anything affecting modulation quality. Different materials also would require different equipment for simulation and test.

There is a lot of activity between government and industry on this today. But you do have to worry about the physical durability of a device, which could include everything from de-lamination to physical degradation like cracking when it is exposed to a harsh environment.

You also have to figure out if heat is going to be a problem—do you need to create a heat-resistant flexible substrate—and does it need to be transparent.

Conclusion Printed electronics largely has been a science project in the past. How quickly, for which applications, and where problems may erupt are still to be determined.

But the ability to put electronics into any environment, regardless of the shape or environmental conditions, and to be able to obtain more data than through traditional chips is a very attractive set of attributes for many applications.

That set of attributes is only likely to grow as the kinks are worked out of the supply chain and reliability simulation and testing are proven to be sufficient for quality assurance. Printed Electronics Materials. This is only fitting, seeing as the field of printed electronics was invented in this way, by combining traditional techniques from the printing industry with electronics. Similar to conventional printing, printed electronics applies ink layers one atop another.

There are a few main areas where key advances in printed electronics are happening. Research and development focuses on the improvement of printing processes and equipment, development of materials with particular properties, design and integration of hardware, and software development.

Printed electronics technology is designed by making changes or innovations to each, or several of these features in conjunction to solve new problems, or by adapting these to meet particular product specifications. One of the reasons the printed electronics market can be slow to innovate, is that developing novel technology can require collaboration between different stages of the supply chain or technology stack, for example the paint chemistry or hardware development.

This presents a unique opportunity for companies such as Bare Conductive. Our focus on Dynamically Functional Surfaces as a complete solution makes us uniquely suited to address market needs from the bottom up, delivering complete outcomes that encompass material selection, sensor and hardware and industrial design, all the way to software development and connection to the cloud.

At Bare Conductive we believe the most interesting opportunity for printed electronics today is in the creation of smart buildings through the integration of printed circuits, flexible displays, sensors, and other electronic components into the built environment. However, there are many challenges to seamlessly integrating printed electronics into industry standard functional materials such as drywall, wallpaper, flooring and roofing.

Some of the challenges associated with these applications include substrate and material selection, paint deposition, printing patterns, hardware integration and software development.

There are many things to consider when designing solutions around all these factors. For example:. Substrate and conductive ink — Developing solutions for smart buildings requires leveraging standard manufacturing processes and materials to take ad existing supply chains and minimize cost. Because of this, when selecting conductive coatings it is critical to select materials that make use of an existing printing method.

The challenge lies in understanding what materials and manufacturing processes are best suited for standardizing the manufacture of smart building materials. Printing patterns — When designing printed electronics, pattern design is a critical factor. The challenge lies in developing the most effective pattern for a particular use-case or environment.

Hardware integration — Hardware is full of challenging opportunities for printed electronics. These range from the development of small or flexible electronic components that can be easily incorporated into printed electronic devices, to the design and manufacture of connectors that enable a robust and reliable link between rigid hardware and a flexible substrate.

Software development — Although not relevant for all printed electronics applications, when dealing with sensors and IoT devices which need to connect to building management systems or to the cloud, developing software becomes a critical part for ensuring a robust printed electronics stack.

Another challenge facing printed electronics is the lack of awareness of the applications and benefits these technologies can bring to fields not traditionally associated with electronics, and how these technologies can be harnessed and integrated into existing manufacturing processes. By commercializing development kits, and making our technology accessible to designers, engineers and creatives, we put printed electronics in the hands of the broadest possible audience, stimulating an open channel for experimentation and exploration.

The end-use markets for printed electronics include automotive and transportation, consumer electronics, healthcare, retail and packaging, aerospace and defense, construction and architecture. For most of these markets, the attraction of printing technology for the fabrication and integration of electronic components mainly comes from the possibility of preparing stacks of micro-structured layers in a much simpler and cost-effective way compared to conventional electronics.

These thin and flexible devices can facilitate widespread low-cost electronics for applications such as smart surfaces with integrated interfaces and switches, inbuilt occupancy sensors, discrete water sensors, flexible displays, smart labels, interactive walls, and active clothing and wearables. Printing enables low-cost manufacturing at large scale, like in RFID-systems which enable contactless identification in trade and transport.

Printing on flexible substrates allows electronics to be placed on curved surfaces, for example, printing solar cells on vehicle roofs, or the integration of buttons and switches into one part, such as a vehicle door, reducing cost in materials, assembly and part count. In some cases although cost is not lowered, like with conventional semiconductors, the higher cost is justified through much higher performance.

Printed electronics allows the use of flexible substrates, which lowers production costs and allows fabrication of mechanically flexible circuits. In the health sector, besides the development of non-intrusive wearables and monitoring devices, printed electronics has the potential improve health outcomes by tackling hygiene, infection and transmission.

Printed electronics offer the ability to create integrated touch-less interfaces using hygienic materials, allowing for the design of surfaces such as keypads, controls or light switches which can be easily cleaned and disinfected.
