对低成本、柔性、生物相容性、可生物降解和自供电的压力传感器的需求正在增加，特别是在软机器人、假肢和植入式电子应用中的应用。然而，大多数压力传感器缺乏生物降解性和生物相容性，导致电子废物增加。此外，大多数现有技术的压力传感器需要外部电源用于其操作，并且体积庞大，进一步使其不适合于可穿戴和可植入的电子应用。为了解决这些限制，需要开发一种利用生物蛋白质的新型自供电压力传感器，壳聚糖具有柔韧性、生物降解性和高灵敏度。该传感器将能够准确有效地检测和响应不同的压力水平，具有高机械灵活性和可重复性。本文概述的战略介绍了一种创新的生物材料，为下一代可穿戴设备、植入式设备、软机器人和生物医学等各种应用提供了重要的实用性。
The demand for low-cost, flexible, biocompatible, biodegradable, and self-powered pressure sensors is increasing, particularly for applications in soft robotics, prosthetics, and implantable electronic applications. However, most of the pressure sensors lack in terms of biodegradability and biocompatibility resulting in increased electronic waste. Further, most of the state-of-the-art pressure sensor need an external power supply for its operation and are bulky further making it not suitable for the wearable and implantable electronic applications. To address these limitations, there is a need to develop a novel self-powered pressure sensor that utilizes bio-proteins i.e., Chitosan offering both flexibility, biodegradability, and high sensitivity. This sensor will enable accurate and efficient detection and response to varying levels of pressures, with high mechanical flexibility, and repeatability. The strategy outlined here introduce an innovative biomaterial, offering significant utility for various applications such as next-generation wearables, implantable devices, soft robotics, and biomedical.
