Abstract

Hydrogels are widely used in flexible energy storage and human state detection. As environmental protection requirements continue to increase, the degradability of hydrogels needs to be further improved. In this study, by introducing green starch into acrylamide (AM) and tannic acid (TA), the synergistic improvement of degradability, flexible energy storage and intelligent human motion state detection is achieved. These hydrogels were then assembled into supercapacitors, which achieved a capacitance of 340.4 F g−1 at a current density of 0.8 mA cm−2, with a capacitance retention rate of 83.5 % after 3000 cycles. As flexible sensing devices, the hydrogels exhibited a response time of 0.16 s and provided consistent real-time resistance change rates in response to various strains, yielding a gauge factor of 3.77. Thus, this starch based hydrogls (SAT) demonstrated promising applications as both Morse code encoders and intelligent manipulator based on deep learning, which cast lights on multifunctional flexible devices.

集柔性超级电容器和智能人体活动状态监测于一体的绿色淀粉基自分解水凝胶

水凝胶广泛应用于柔性储能和人体状态检测。随着环保要求的不断提高，水凝胶的可降解性有待进一步提高。本研究通过将绿色淀粉引入丙烯酰胺（AM）和单宁酸（TA）中，实现了可降解性、柔性储能和智能人体运动状态检测的协同提升。然后将这些水凝胶组装成超级电容器，在0.8 mA cm−2的电流密度下，电容达到340.4 F g−1，循环3000次后电容保持率为83.5%。作为柔性传感器件，水凝胶的响应时间为0.16 s，对各种应变的响应具有一致的实时电阻变化率，测量因子为3.77。因此，这种淀粉基水凝胶（SAT）在莫尔斯电码编码器和基于深度学习的智能机械臂方面都有很好的应用前景，为多功能柔性设备带来了希望。
