Good breathability and antibacterial properties are among the key prerequisites for applying flexible sensors to electronic skins or similar devices. As such, these features hot topics ongoing research. In this paper, a three-dimensional (3D) thermoplastic polyurethane (TPU) fiber network backbone was constructed by using electrostatic spinning technique. Then, silver nanoparticles (AgNPs) were deposited on via an in situ reduction reaction with AgNO3 form 3D conductive network. From reaction, highly sensitive multifunctional sensor excellent obtained. The sensor's efficient shown give sensor: fast response (21 ms) recovery times (43 ms); high conductivity (4600 S/m); gauge factor (GF = 9.52 × 104); low strain detection limit (0.05%); wide operating range (0.05–120%). A water vapor permeation test demonstrated that synthesized transmission rate (WVT) 2209 g–2 day–1, which is approximately four higher than of human skin. Additionally, vitro activity assay revealed diameter inhibition circle both Escherichia coli Staphylococcus aureus expanded 4.17 5.67 cm, respectively, as result effect particles surface.

Abstract Mechanoluminescence (ML) sensing technologies open up new opportunities for intelligent sensors, self-powered displays and wearable devices. However, the emission efficiency of ML materials reported so far still fails to meet growing application requirements due insufficiently understood mechano-to-photon conversion mechanism. Herein, we propose quantify ability different phases gain or lose electrons under friction (defined as triboelectric series), reveal that inorganic-organic interfacial triboelectricity is a key factor in determining composites. A positive correlation between difference series intensity established composites, 20-fold increase finally obtained by selecting an appropriate combination. The triboelectricity-regulated further demonstrated multi-interface systems include inorganic phosphor-organic matrix organic matrix-force applicator interfaces, again confirmed self-oxidization reduction centers continuous mechanical stimulus. This work not only gives direct experimental evidences underlying mechanism ML, but also provides guidelines rationally designing high-efficiency materials.

Touch control intention recognition is an important direction for the future development of human-machine interactions (HMIs). However, implementation parallel-sensing functional modules generally requires a combination different logical blocks and circuits, which results in regional redundancy, redundant data, low efficiency.

The LPI eliminates need data transfer among units through core integration design layered structure. It actuates in-sensor perception feature transmission, fusion, differentiation, thereby revolutionizing traditional von Neumann architecture. While greatly simplifying dimensionality, achieves outstanding resolution sensing both location (<400 µm) pressure (75 Pa).
