Abstract Self‐powered wearable sensors play a vital role in various fields such as healthcare, sports science, ergonomics, and virtual reality. In this study, we present flexible self‐powered pressure sensor based on piezoelectric triboelectric effects. The multilayer features structure comprising polyethylene terephthalate (PET) layer with controllable microstructure, composite nanofiber using polyvinylidene fluoride (PVDF) multiwall carbon nanotubes (MWCNTs) fabricated via electrospinning, conductive fiber layers electrodes. sensitivity of the triboelectric–piezoelectric hybridized can reach twice that original sensor. exhibits excellent at 48.48 mv/kPa maintains stability after 10 000 cycles. Due to super‐flexibility biocompatibility, be comfortably attached human body. Furthermore, is capable recognizing movements through corresponding electrical signals. This holds promising application potential areas gesture recognition, health assessment, human‐machine interfaces, more.

Biodegradable foams possess diverse applications in smart wearables, flexible sensors, and human–computer interaction. Current sensors face the problems of inadequate stress/strain sensitivity, high density, content conductive filler. In this study, microcellular poly(butylene adipate‐co‐terephthalate) (PBAT)/polyether block amides (PEBA)@multi‐walled carbon nanotube (MWCNT) sensor exhibiting resilience, low filler was prepared via foaming molding integration. integration process, PBAT/PEBA beads achieve efficient bonding inter‐beads, where PBAT molecular chains interfacial diffusion entanglement as well PEBA improve stability mechanical properties product. MWCNT is coated on surface beads, forming a segregated structure good network by ball‐milling technique. Consequently, PBAT/PEBA@MWCNT demonstrates exceptional piezoresistive with strain response gauge factor 60.0 stress 0.1 kPa −1 . The time recovery reach 50 100 ms, respectively. Microcellular shows promising potential for detecting various human body parts, including fingers, knees, arms. This study presents an effective approach fabrication prospective application highly sensitive degradable sensors.
