Recent advances in flexible electronics have brought great promotions to the next generation of wearable devices, like electronic skin (E-skin). Nevertheless, the powering issue still limits the size, weight and cost for E-skin. Here, trampoline inspired mechanics design and processing techniques in epidermal electronics are combined together to develop a thin, soft, stretchable self-powered tactile sensors based on triboelectric effect for E-skin. With the assistance of microstructure modifying by sandpapers, the TENG sensor exhibits great improved electrical performance and capable of distinguishing a broad range of pressure, with a great sensitivity of 0.367 mV Pa−1. The resulted TENG sensor exhibits excellent stretchability and sensing stability with accurate unchanged signal outputs even under a high-level strain up to 35%. Demonstrations of the sensors associating with the integration with a glove for human-machine interfaces and the development of a 4 × 4 tactile array for pressure mapping and recognition of contact objects, offers great opportunity for next generation self-powered E-skin.

蹦床启发的可拉伸摩擦电纳米发电机作为表皮电子设备的触觉传感器
柔性电子产品的最新进展为下一代可穿戴设备(如电子皮肤(E-skin))带来了巨大的提升。然而,供电问题仍然限制了电子皮肤的尺寸,重量和成本。在这里,表皮电子学中受蹦床启发的机械设计和处理技术结合在一起,从而基于电子皮肤的摩擦电效应,开发出了薄,柔软,可拉伸的自供电触觉传感器。借助砂纸进行的微结构改性,TENG传感器具有出色的电气性能,能够区分各种压力,灵敏度高达0.367 mV Pa -1。所得的TENG传感器即使在高达35%的高水平应变下,仍具有出色的可拉伸性和感测稳定性,并具有准确的信号输出不变。与人机界面手套集成相关联的传感器的演示以及用于压力映射和识别接触物体的4×4触觉阵列的开发,为下一代自供电电子皮肤提供了巨大的机会。
