The demand for tactile sensors in robotics, virtual reality, and health care highlights the need for high performance and customizability. Despite advances in vision-based technologies, tactile sensing remains crucial for precise interaction and subtle pressure detection. In this work, we present a design and fabrication method of customizable tactile sensors based on thermoformed three-dimensional electronics. This approach enables ultrawide modulus tunability (10 pascals to 1 megapascal) and superior mechanical properties, including negligible hysteresis and high creep resistance. These features allow the sensor to detect a broad spectrum of pressures, from acoustic waves to body weight, with high performance. The proposed sensors have high sensitivity (up to 5884 per kilopascal), high linearity ( = 0.999), low hysteresis (<0.5%), and fast response (0.1 milliseconds). We demonstrate applications in human-computer interaction and health care, showcasing their potential in various fields. This platform provides a scalable solution for fabricating versatile, high-performance tactile sensors.
机器人技术、虚拟现实和医疗保健领域对触觉传感器的需求凸显了对高性能和可定制性的需求。尽管基于视觉的技术取得了进展，但触觉传感对于精确交互和细微压力检测仍然至关重要。在这项工作中，我们提出了一种基于热成型三维电子器件的可定制触觉传感器的设计和制造方法。这种方法能够实现超宽的模量可调性（10帕斯卡至1兆帕斯卡）以及优异的机械性能，包括可忽略不计的滞后现象和高抗蠕变性。这些特性使传感器能够以高性能检测从声波到体重的广泛压力范围。所提出的传感器具有高灵敏度（高达每千帕斯卡5884）、高线性度（ = 0.999）、低滞后现象（<0.5%）和快速响应（0.1毫秒）。我们展示了其在人机交互和医疗保健中的应用，突显了它们在各个领域的潜力。该平台为制造多功能、高性能触觉传感器提供了一种可扩展的解决方案。
