Flexible Hybrid Electronics (FHE), heterogeneous electronics embodying both conventional silicon electronics and printed electronics, is an emerging technology with huge market potential as it is advantageous compared to conventional silicon electronics and the emerging Printed Electronics - FHE features better mechanical flexibility/conformability and lower cost compared to conventional silicon electronics, and higher performance compared to Printed Electronics. In this paper, a comprehensive literature view on FHE is provided, including the state-of-the-art FHE development, FHE supply chains, and design challenges.
