Moisture detection plays a crucial role in physiological monitoring and wearable electronics. Nevertheless, most of the humidity sensors were restricted by power supply, hindering their applicability internet things mobile healthcare. Herein, we reported hierarchical piezoelectric composite film for active biomonitoring. The as-electrospun transducing textile consists samarium-modified lead magnesium niobate titanate piezoceramic fillers polyvinylidene fluoride matrix, while spin coated polyimide serves as sensitive layer. By tuning thickness ratio between layer sensing well porosity electrode, an optimal moisture-sensing performance was accomplished with high response ∼500% rapid response/recovery time 23 s/31 s. Furthermore, theoretical modeling mechanism established combining thermodynamic derivation finite element calculation.

Abstract Skin‐like thermoelectric (TE) films with temperature‐ and strain‐sensing functions are highly desirable for human‐machine interaction systems wearable devices. However, current TE still face challenges in achieving high flexibility excellent sensing performance simultaneously. Herein, the first time, a facile roll‐to‐roll strategy is proposed to fabricate an ultraflexible chalcogenide glass‐polytetrafluoroethylene composite film superior performance. The unique reticular network of endows it efficient Seebeck effect flexibility, leading coefficient (731 µV/K), rapid temperature response (≈0.7 s), strain sensitivity (gauge factor = 836). Based on this high‐performance film, intelligent robotic hand action feedback alarm fabricated, demonstrating its great potential interaction. Such fabrication not only brings new inspiration inorganic devices, but also sets stage wide implementation multifunctional systems.

Quick response and high sensitivity are equally important for the practical application of gas sensors. In this study, we introduced polyoxometalates (POMs) into a classical ternary metal oxide CuBi2O4 first time by convenient electrospinning prepared group heater-type sensors using CuBi2O4/PW12 composite nanofibers. The sensor performances to formaldehyde were explored. results proved that gas-sensing (PW12 = H3PW12O40·xH2O) 100 ppm was increased 6.68, which 3.92 times greater than sensing capacity pure sensor. Simultaneously, exhibited highly rapid response/recovery only 1/2 s, is significantly faster reported in past literature. cause improvement performance assessed via mechanism it found introduction PW12 contributed its enhanced performance. It PW12, as an electron acceptor, carrier mobility reduced electron–hole recombination, thus contributing properties. Moreover, other parameters such selectivity, humidity resistance, repeatability, long-term stability investigated. Hence, study literature on development polyoxometalates-based

Polymer-based piezoelectric composites have shown a large potential in various fields of wearable electronics, man–machine interaction, transducers, etc., due to their integrated advantages high properties, benign flexibility, and pressure sensitivity. As the representative polymer matrix composites, polyvinylidene fluoride (PVDF) is characterized by its intrinsic response induced via existence ferroelectric β γ phases. However, most stable phase at ambient temperature nonpolar paraelectric α phase, which serves as long-standing issue. Herein, chitosan was introduced into PVDF promote transition from interaction between –OH –NH2 groups H F atoms PVDF. evidenced, portion increased 47.9 63.7%. An electrospinning technique adopted prepare PVDF/chitosan with content ranging 1 4 wt %, correlation structural characteristics properties illustrated detail.
