Flexible piezoelectric sensor based on ATO/BNT multi-layers with high sensitivity, thermal healing and driving performance

A Review of Recent Advances in Human-Motion Energy Harvesting Nanogenerators, Self-Powering Smart Sensors and Self-Charging Electronics

“…Future outlooks: More emphasis should be placed on material selection and structure design to create a system that will operate for a long time without significant performance loss. One idea is to use materials that exhibit self-healing properties as friction layers or fully healable nanogenerators and extend them to large-sized devices [ 203 , 204 , 205 , 206 ]. Another idea is to implement 3D-printing method that expands possible application tunability and uses a unique, tailor-made device architecture [ 207 , 208 , 209 , 210 ].…”

Boosting Sensing Performance of Flexible Piezoelectric Pressure Sensors by Sb Nanosheets and BaTiO3 Nanoparticles Co‐Doping in P(VDF‐TrFE) Nanofibers Mat

“…For example, InN, GaN, BaTiO 3 (BTO), (K, Na)NbO 3 , Bi 0.5 Na 0.5 TiO 3 . [ 7–9 ] And in order to achieve a good skin‐fitting properties, recently, polyvinylidene fluoride (PVDF) and its copolymers have found a large number of applications in self‐powered wearable devices, electronic integrated devices, etc. [ 10,11 ] PVDF‐based polymers have five phases of crystallization, α, β, γ, ε, and δ, among which the β phase has an all‐trans structure (TTTT), while the H and F atoms on the chain segment show a 180° flip to form a dipole, and the external pressure causes a change in the dipole moment, thus exhibiting the maximum piezoelectric properties.…”
