| 제목 | NIR/pH Controlled Stretchable, Conductive, and Self-Healable Hydrogel for Self-Powered Skin Sensor with Amplified Human Motion Sensing Performance |
| 초록 | Here, we have developed a reusable electronic skinsensor fromNIR/pH-responsive polymer dot (PD) embedded hydrogel that shows enhanced mechanical, electrochemical, and amplified sensingperformance with prolonged lifetimes of the sensor after NIR/pH-driven self-healing. The tunability isachieved by controlling the hydrogen bond formation with regulating mobilityfrom the PD units. Hydrogel produced at pH 7.4, after treatment with pH 10 andhealed with NIR, mechanical expansion (585%), electrical conductivity (6.8 mScm–1), and capacitance (184.2 mF cm– 2), increased by 125%, 4.9 times, and 37% respectively. The fabricated strain sensor has shown excellent sensitivityof 0.36 kPa–1 with remarkable stability over 12000stretching-bending cycles. Furthermore, the hydrogel supercapacitor was attachedwith a solar cell device and a self-power body sensor was achieved with anoverall efficiency of 2.32%. |
