Abstract

Inspired by the multimodal perception of human skin, flexible sensors are advancing intelligent sensing systems in healthcare and robotics. Pressure-temperature bimodal sensing is crucial for enhanced environmental perception and cross-domain applications. However, critical challenges remain in interference suppression and effective integration for augmented tactile and thermal perception. Here, we propose an interference-free flexible intelligent sensing patch that is composed of a laser-patterned pressure sensor and a thermistor. The patch demonstrates a large pressure detection range of 8 Pa to 220 kPa with a rapid response time of 50 ms, and a high temperature-sensing resolution of 0.01 °C at the range of 10–50 °C. Additionally, it can maintain highly stable performance under 150° bending deformation and 10% tensile strain. Furthermore, we built an integrated real-time processing platform to demonstrate its versatility through continuous, non-invasive monitoring for wrist pulse and epidermis temperature. Impressively, the patch can enhance real-time tactile feedback for soft robotic grippers during object manipulation, achieving tactile recognition with an accuracy of 94.09% for ten distinct objects. Intelligent sensing patches for augmented tactile and thermal perception hold promises for delivering precise and natural experiences while driving innovation and advancement in artificial prosthetics, intelligent robotics, wearable devices, and health monitoring.

柔性智能传感贴片增强触觉和热感知

受人体皮肤多模态感知的启发，柔性传感器正在推进医疗保健和机器人领域的智能传感系统。压力-温度双峰传感对于增强环境感知和跨域应用至关重要。然而，关键的挑战仍然存在于干扰抑制和增强触觉和热感知的有效整合。在这里，我们提出了一种无干扰的柔性智能传感贴片，它由激光图纹压力传感器和热敏电阻组成。该贴片具有8 Pa ~ 220 kPa的大压力检测范围，快速响应时间为50 ms，在10-50℃范围内具有0.01℃的高温传感分辨率。此外，在150°弯曲变形和10%拉伸应变下仍能保持高度稳定的性能。此外，我们建立了一个集成的实时处理平台，通过对手腕脉搏和表皮温度的连续、无创监测来展示其多功能性。令人印象深刻的是，该贴片可以增强软机器人抓手在物体操作过程中的实时触觉反馈，对10个不同物体的触觉识别精度达到94.09%。用于增强触觉和热感知的智能传感贴片有望提供精确和自然的体验，同时推动人工假肢、智能机器人、可穿戴设备和健康监测领域的创新和进步。
