Advantages of printed electronics

Mass production by roll to roll
Final product doesn’t need to be flexible. Eg: glucose test strip
Large area electronics
Additive manufacturing reduces material waste. Eg: in-moldelectronics, displays
Flexible plastic substrates
Form factor becomes USP. Eg: wearable components, bend sensors

Simple resistor circuit and thermochromic displayOther smart packaging experiments have been less successful (often for limited edition only)
Success stories: battery testers

Over 20 billion glucose test strips produced annually for diabetes managementRoll to roll printing ideal for mass productionHowever, market is now commoditizedTechnology is moving to artificial pancreas and other forms of monitoring
Success stories: glucose test strips

Most common is temperature sensor. Others include humidity, shock, pressure or moisture.Four configurations currently:o Passive RFID sensors o Passive RFID sensors (battery assisted)o Passive RFID tags with sensing film o "Chipless" RFID - without a conventional silicon IC
RFID adds sensing capabilities
“The market value of RFID sensor tags will be $490 million by 2027”

Printed electronics not just for flexible devices
Past success stories were mostly based on simple devices with a focus on minimizing production costs
Future applications will be based on advanced materials and complementarity with silicon electronics
