Printed Built-In Power Sources (Printed Electronics Europe 2020)

Prof Sang-Young Lee, CTO

Presentation Summary

The upcoming smart electronics/the Internet of Things (IoT) era spurs the relentless pursuit of high-performance power sources with various form factors. Printed power sources have recently garnered considerable attention due to their exceptional shape diversity and process simplicity. This presentation will describe a new class of form factor-free, printed built-in power sources which can be monolithically integrated devices.
