随着物联网与人工智能的快速发展，人机交互在医疗辅助、智能家居等领域应用广泛. 柔性压力传感器因其能将压力精确转换为电信号而成为研究热点. 然而，当前柔性压力传感器在人机交互中仍面临响应速度不足及多单元传感器电极数量多、布线复杂、制备成本高等问题. 针对上述挑战，本文提出一种基于短接效应的可印刷式柔性压力传感器，采用双电极单通道架构实现多传感单元集成. 传感器利用商用导电浆料通过丝网印刷工艺制备，具备良好的环境稳定性与批量化生产潜力. 多个传感单元在受压时产生差异明显的电阻信号，可实现位置精准识别. 该传感器响应时间为8 ms，恢复时间为9 ms，经1000次按压循环电阻波动小于1%，展现出优异的快速响应与机械稳定性. 作为概念验证，将16个传感单元集成并应用于虚拟逻辑计算器，验证了其在人机交互中的应用潜力. 提供了有效策略.
Abstract：With the rapid advancement of the Internet of Things (IoT) and artificial intelligence(AI)， human–machine interaction (HMI) has found extensive applications in fields such as medical assistance and smart homes. Flexible pressure sensors have become a research focus due to their ability to accurately convert pressure into electrical signals. However， current flexible pressure sensors for HMI still face challenges including insufficient response speed， a high number of electrodes in multi-unit sensors， complex wiring， and high fabrication costs. To address these issues， this paper proposes a printable flexible pressure sensor based on the "short-circuit" effect， which integrates multiple sensing units using a two-electrode， single-channel architecture. The sensor is fabricated via screen printing using commercial conductive pastes， exhibiting good environmental stability and potential for mass production. Multiple sensing units generate distinctly different resistance signals upon pressure application， enabling accurate position identification. The sensor demonstrates a response time of 8 ms and a recovery time of 9 ms， with a resistance fluctuation of less than 1% over 1000 pressing cycles， showcasing excellent rapid response and mechanical stability. As a proof of concept， 16 sensing units were integrated and applied to a virtual logic calculator， validating its potential for HMI applications.
