Flexible, air permeable and elastic self-powered sensors for human motion monitoring assisted medical rehabilitation have recently become a hot research topic. However, most current piezoelectric can not account many characteristics. Addressing this challenge, an all-textile sensor (ATPS) based on 3D structured knitted fabric electrodes is reported. The ATPS consists of element polyvinylidene fluoride nanofiber membrane, flexible electrodes, self-adhesive bandage. Based the efficient knitting technology, has advantages low cost, flexibility, simple structure, convenient large-area manufacturing. Experimental finite simulation results show that pattern enhance output ATPS. optimal high voltage response sensitivity up to 0.68 V/kPa. proposed responds wide range input forces from 0.098 724 N in mode, verifying its feasibility as tactile detection recognition (throat swallowing, wrist bending, elbow knee walking slowly, running fast) pressure (Morse code, digit recognition) demonstrating potential tracking, rehabilitation, human-computer interaction.

Much progress has been made toward the development of wearable flexible strain sensors with high sensing performance to monitor human motion, but continuous function in harsh aqueous environments remains a significant challenge. A promising strategy design highly durable superhydrophobicity and maintenance unique properties. Herein, an extremely superhydrophobic sensor ultrawide range was simply fabricated by directly brushing conductive carbon black nanoparticles (CBNPs) onto elastic silicone rubber sheet (SS) poly(dimethylsiloxane) (PDMS) coatings (i.e., SS/PDMS-CBNPs sensors). First, this method avoided use toxic solvents conventional prestretching treatment. Second, considering easily destroyed rough structures surface chemistry for during practical applications, prepared SS/PDMS-CBNP showed excellent mechanical durability both as examined abrasion (300 cycles), stretching (up 200%), ultrasonication (40 min) treatments. Third, exhibited sensitivity (gauge factor 101.75), stretchability (0.015-460%), low hysteresis (83 ms), long-term stability (10000 cycles). Fourth, biocompatibility demonstrated rabbit skin irritation tests. Finally, remarkable water-repellent properties allowed its application swimmer's real-time situation send distress signals when needed.
