Thick Film Printing for Flexible Circuits in Wearable Devices

Abstract

The presence of flexible circuits in wearable electronics, especially medical devices, has been expanding. The thick film printing process has been becoming the key technology in this area. Advantages and disadvantages of the technology were evaluated comparing with traditional photolithography and etching process. The thick film printing process is able to generate functional circuits employing new unique materials. Several examples were introduced to show the mechanisms of the printed devices.
