Stretchable and flexible tactile sensors have been extensively investigated for a variety of applications due to their outstanding sensitivity, flexibility, and biocompatibility compared with conventional tactile sensors. However, implementing stretchable multimodal sensors with high performance is still a challenge. In this study, a stretchable multimodal tactile sensor based on conductive rubber composites was fabricated. Because of the pressure-sensitive and temperature-sensitive effects of the conductive rubber composites, the developed sensor can simultaneously measure pressure and temperature, and the sensor presented high sensitivity (0.01171 kPa and 2.46-30.56%/°C) over a wide sensing range (0-110 kPa and 30-90 °C). The sensor also exhibited outstanding performance in terms of processability, stretchability, and repeatability. Furthermore, the fabricated stretchable multimodal tactile sensor did not require complex signal processing or a transmission circuit system. The strategy for stacking and layering conductive rubber composites of this work may supply a new idea for building multifunctional sensor-based electronics.
与传统触觉传感器相比，可拉伸且灵活的触觉传感器因其出色的灵敏度、柔韧性和生物相容性，已被广泛研究用于各种应用。然而，实现高性能的可拉伸多模态传感器仍然是一项挑战。在本研究中，制备了一种基于导电橡胶复合材料的可拉伸多模态触觉传感器。由于导电橡胶复合材料的压敏和热敏效应，所开发的传感器能够同时测量压力和温度，并且该传感器在较宽的传感范围（0 - 110 kPa和30 - 90 °C）内呈现出高灵敏度（0.01171 kPa和2.46 - 30.56%/°C）。该传感器在可加工性、可拉伸性和重复性方面也表现出色。此外，所制备的可拉伸多模态触觉传感器不需要复杂的信号处理或传输电路系统。这项工作中堆叠和分层导电橡胶复合材料的策略可能为构建基于多功能传感器的电子设备提供新思路。
