Abstract

Torque sensors are essential components of robotic joints. In the past, structure optimization of force-sensing elements has been the common approach to improve the performance of the torque sensors. In this work, we demonstrate a torque sensor with bulk metallic glasses as a force-sensing element. Compared with the sensors made of stainless steel and aluminum alloy, the use of bulk metallic glass as a force-sensing element significantly improves sensor sensitivity, linearity, repeatability, hysteresis, and measuring range. Our work not only opens up a new avenue for the application of bulk metallic glasses, but also provides opportunities for enhancing the performance of force/torque sensors through materials optimization.

块状金属玻璃在扭矩传感器中的应用前景广阔

扭矩传感器是机器人关节的重要组成部分。过去，力感应元件的结构优化是提高扭矩传感器性能的常用方法。在这项工作中，我们展示了一种采用块状金属玻璃作为力感应元件的扭矩传感器。与不锈钢和铝合金制成的传感器相比，使用块状金属玻璃作为力感应元件可显著提高传感器的灵敏度、线性度、重复性、滞后和测量范围。我们的工作不仅为块状金属玻璃的应用开辟了一条新途径，而且为通过材料优化提高力/扭矩传感器的性能提供了机会。
