A flexible metal nano-mesh strain sensor with the characteristic of spontaneous functional recovery after fracture damage

Abstract

Developing flexible sensors with high sensitivity, wide sensing range, and good stability is a challenge. By replicating the anodic aluminum oxide (AAO) hole structure, we proposed new strain sensors with...

Recent advances in the material design for intelligent wearable devices

“…90 The PDMS/Cu nanowire films exhibited impressive conductivity, endowing them with potential applications in wearable devices. With the rapid development of flexible electronics, advanced manufacturing techniques for metal-based materials have been rapidly developed, including printed metal, 91 nanometallic inks, 92 and the braiding of metallic wires, 93 allowing them to be combined into a deformable flexible substrate. The integration of metal-based materials is usually implemented via a layer-by-layer strategy, and the prevailing approach is to load thin metal foils onto polymer substrates by spin-coating to design flexible, complex multilayer sensors.…”

Flexibly stretchable acrylic resin elastomer films for efficient electromagnetic shielding and photothermal conversion

“…[6][7][8][9][10][11][12][13] At the same time, with the rapid development of information technology and communication equipment, exible intelligent wearable electronic devices with self-heat or swi heat dissipation property are attracting close attention from researchers. 14 Wearable electronic devices can be used for medical diagnosis, 15 physiological activity monitors, 16 exible robots, 17,18 etc. In order to enhance the signal stability and reduce the radiation of wearable electronic devices, as well as ensure the self-heating and heat dissipation properties, it is urgent to develop composites with excellent EMI shielding performance and efficient thermal management.…”

A double-crack structure for bionic wearable strain sensors with ultra-high sensitivity and a wide sensing range

“…Furthermore, people can arbitrarily arrange them according to the requirements of measurement conditions due to the various structures of flexible sensors. At present, flexible strain sensors are extensively used in the development of electronic skin, [10][11][12][13] healthcare, 14,15 voice recognition, 16,17 sports equipment, 18,19 triboelectric nanogenerators, 20 textiles, 21,22 aerospace, 23 environmental monitoring 24,25 and other fields. 26,27 Generally, the sensing performance of flexible strain sensors can be evaluated using various performance parameters such as sensitivity [gauge factor (GF)], stretchability (sensing range), linearity, hysteresis, response time, and dynamic stability.…”
