There is a somewhat warranted perception that printed electronics have never quite lived up to the hype. There are many examples of printed electronics in our lives.Printed glucose sensors are a billion-dollar industry. Our vehicles have printed systems, from printed heaters in the seats to seat belt and airbag passenger seat sensors. But the “killer app” has yet to emerge. What has emerged is the flexible hybrid electronics field, essentially taking the best of printed and traditional electronics. This has long been the approach for RFID. By printing the conductive traces such as antennas and placing a silicon chip on them, manufacturers can get the best of both worlds. This is opening up new opportunities in healthcare-related sensors and wearables. The more flexible the system, the more comfortable it will be in a wearable or the more usable in a conformable display. Sensors have proven to be a strong opportunity. During the COVID-19 pandemic, numerous companies came u
