 we present a strategy to build a star-nose-inspired sensor with stretchable and twistable structure, where the nose’s ray-like parallel polyimide films were fabricated by electrospinning and chemical silver coating. The sensor is finally encapsulated in PDMS and its sensitivity is significantly improved due to the design of bio-inspired parallel films. The bio-inspired sensor finally exhibits ultra-light, ultra-thin, and high sensitivity (Gauge Factor (GF) ~ 4000) characteristics, ensuring a perfect fit for human skin to achieve stretch, twist (https://www.sciencedirect.com/science/article/pii/S2211285520311332)

Wearable thermoelectric energy harvester by using waste heat from human body. we report a stretchable TEG (S-TEG) (over 50% stretchability of the entire device) that is geometrically suitable for various complex and dynamic surfaces of heat sources. The S-TEG consists of hot-pressed nanolayered p-(Sb₂Te₃) and n-(Bi₂Te₃)-type thermoelectric couple arrays and exploits the wavy serpentine interconnects to integrate all units. (https://pubs.acs.org/doi/full/10.1021/acs.nanolett.0c01225)
