ABSTRACT
Flexible hybrid electronics (FHE) is an innovative technology that requires advanced fabrication processes that combine printed sensors and circuits with traditional integrated circuits (ICs) on flexible, stretchable substrates. This chapter summarizes recent developments in the field of passive sensors printed on flexible substrates for FHE systems from the perspective of mixed-signal IC design. Passive devices used as sensors in complementary metal oxide semiconductor (CMOS) technologies are introduced, as well as passive printed devices (resistors, capacitors, and inductors) on flexible substrates along with applications to illustrate similarity in their implementation. Potential products include wearable devices for monitoring patient health or novel bioelectronics implants that conform to the underlying geometry of biological tissue and organs in the body.
