Micro‐Pore Composed Soft Pressure Sensor with Ether‐Surfactant via High‐Sensitivity in Wide Range for Robotic Machine Interface Application

Abstract

Abstract Robotic machine interfaces with sensor devices in robotics applications can facilitate the proper handling of objects. The wide‐range responses of the sensors are important for achieving statement of recognition in tactile sensing systems. Thus, this study proposes a novel micro‐pore‐induced soft pressure sensor via wide‐range response by synthesizing functional composite materials with ether‐surfactant and conductive materials. The aim is to produce soft pressure sensors that are highly responsive and exhibit a wide sensitivity range for the detection of an applied pressure. The sensor comprises a multiwalled‐carbon nanotube, an ether‐based surfactant, and polymeric soft materials, which exhibit high‐speed response characteristics because of the microporous structure of the sensing layer. Moreover, a novel wearable robotic machine interface for facilitating object manipulation is achieved. Furthermore, the findings of this study in terms of the performance of the robotic‐tactile sensing sensor confirm its suitability for the machine interface of an artificial perception system. Furthermore, a real‐time tactile sensing system using the manufactured sensor in the form of wearable e‐skins is experimentally demonstrated.
