Flexible Sensors with Robust Wear-Resistant and Sensing Ability: Insight on the Microcrack Structure, Multiple Interfacial Bonds, and Possible Sensing Mechanisms

“…The ongoing use of flexible and wearable sensors has engineered sensing materials toward emergent applications, such as human health monitoring, artificial electronic skin, human–machine interactions, speech recognition systems, soft-bodied robots, and so forth. − What makes these materials more adaptable is their suitable substrate and high conductivity that can detect stimuli such as strain, pressure, humidity, and temperature in an ambient environment. For these reasons, various flexible strain/pressure sensors have been developed based on different sensing mechanisms, including triboelectric, piezoelectric, capacitive, and piezoresistive sensing. − The piezoresistive strain/pressure sensor converts external mechanical signals into measurable electrical signals. It has the advantages of simple structure, simple manufacturing process, low cost, and large-scale production.…”

Cicada-Wing-Inspired Highly Sensitive Tactile Sensors Based on Elastic Carbon Foam with Nanotextured Surfaces

“…Compressible and wearable pressure sensory devices have witnessed significant advances over the past 10 years owing to their numerous applications including human motion tracking, personal healthcare monitoring, soft robotics, artificial intelligence, and so forth. − Piezoresistive sensors are regarded as promising candidates for wearable pressure-sensing electronics due to their straightforward design, cost-effectiveness, simplicity of operation, and high compression and deformation sensitivity. − Pressure-sensing devices can convert pressure into variation in resistance, thus realizing the real-time detection of various motions and deformations via the change in current. Recently, flexible polymer and elastomeric films loaded with conducting particles including graphene, , graphite particles, carbon nanotubes (CNTs), − and conducting polymers (such as PEDOT:PSS, polyaniline, and so forth) − have been used as a sensing platform for flexible piezoresistive sensors. − For example, Liu and co-workers fabricated bacteria cellulose (BC) intercalated MXene films using plain paper as a flexible substrate by vacuum filtration. The assembled MXene/BC pressure sensor showed excellent sensing performance including high sensitivity in the low-pressure range, wide linear range, short response/recovery times (99/93 ms), and high stability of 5000 cycles .…”
