摘要
柔性应变片作为一种高灵敏度的传感器,因其轻量化、可拉伸性和良好的贴合性,被广泛应用于可穿戴设备领域,但在动态弯曲或拉伸过程中,应变片的滑移会导致数据不稳定,从而影响测量精度。本研究以植物蛋白玉米醇溶蛋白(Zein)为原料,开发具有粘附作用的生物相适蛋白黏胶,系统探索黏胶组分和制备参数对蛋白黏胶粘附强度的影响。实验结果表明,该黏胶对多种基材(如金属、玻璃、塑料等)均表现出较高的粘附强度。相较于自然湿态下的玉米醇溶蛋白应变片,Zein黏胶的粘附强度提升至3.4倍,达到13.9 kPa。在动态弯曲测试中,Zein黏胶能有效抑制应变片的滑移,使电阻变化率的波动幅度降低,显著提高了传感数据的稳定性。此外,Zein黏胶还表现出良好的可重复粘合能力,在多次循环加载后仍能保持稳定的粘附性能。本研究为生物基黏胶在柔性应变传感器中的应用提供了理论依据和技术支持。
Flexible strain sensors,known for their high sensitivity,have been widely utilized in wearable devices field due to their lightweight,stretchability and excellent conformability.However,during dynamic bending or stretching process,the strain gauge may slip,causing data instability and affecting measurement accuracy.In this study,the plant protein zein was taken as a raw material to develop a bio-compatible protein adhesive with strong adhesive properties,and the influence of adhesive components and preparation parameters on the adhesion strength of the protein adhesive was systematically investigated.The results demonstrated that the adhesive achieved high adhesion strength on various substrates(such as metals,glass and plastics).Compared with the natural wet zein strain sensors,the adhesion strength of the zein adhesive was enhanced to 3.4 times,reaching 13.9 kPa.In dynamic bending tests,the zein adhesive effectively reduced the slip of the strain gauge,decreasing the fluctuation of resistance change rate and significantly improving data stability.Additionally,the zein adhesive showed excellent repeatable bonding capability,maintaining consistent adhesion performance even after multiple loading cycles.The study provided a theoretical foundation and technical support for the application of bio-based adhesives in flexible strain sensors.
