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.
