Tactile sensors have attracted great interest due to the huge potential applications. Skin-like multifunctional capabilities to sense multiple stimuli are increasingly desired to fulfill practical demands. Integration of multiple sensors with different functions is the most common approach, but requiring sophisticated fabricated processes. Here, a self-powered flexible antibacterial tactile sensor has been proposed which is based on triboelectric-piezoelectric-pyroelectric multi-effect coupling mechanism. The triboelectric-piezoelectric-pyroelectric multi-effect is utilized to differentiate external stimuli by analyzing the coupled bimodal voltage signal with response time difference. It permits multifunctional sensing in a single pixel, which can greatly reduce the structural complexity. The sensitivity of pressure and temperature monitoring is 0.092 V/KPa and 0.11 V/°C, respectively. Besides, it can operate without any external power attributing to the sensing mechanisms. Furthermore, the sensor performs excellent antibacterial property by doping Ag nanowires into the contact layer. This work can become promising candidate in soft robotics, artificial prosthetics and healthcare monitors by virtue of multifunctional, self-powered, antibacterial and easy-fabrication merits.

由于巨大的潜在应用，触觉传感器引起了极大的兴趣。为了满足实际需求，越来越需要像皮肤一样的多功能功能来感应多种刺激。集成具有不同功能的多个传感器是最常见的方法，但是需要复杂的制造过程。在此，提出了一种基于摩擦-压电-热电-热电多效应耦合机制的自供电柔性抗菌触觉传感器。通过分析具有响应时间差的耦合双峰电压信号，利用摩擦-压电-热电复合效应来区分外部刺激。它允许在单个像素中进行多功能感测，从而可以大大降低结构复杂性。压力和温度监控的灵敏度为0。分别为092 V / KPa和0.11 V /°C。此外，它可以在没有任何外部电源分配给传感机构的情况下运行。此外，该传感器通过将Ag纳米线掺杂到接触层中而具有出色的抗菌性能。由于具有多功能，自供电，抗菌和易于制造的优点，这项工作可以成为软机器人，人工修复和医疗监护仪中有希望的候选人。
