High‐resolution tactile sensor using the deformation of a reflection image

What is it about?

The research aims to develop a high-resolution tactile sensor capable of measuring contact status with precision. The proposed sensor utilizes the principle of an optical lever and transparent silicone rubber as a deformable mirror surface to maximize the resolution of a camera and leverage reflection images for detection. In simulation, the sensor demonstrates the ability to sense deformations with a 1 percent error rate. However, during the implementation phase, the error rate increases to 10 percent. The findings suggest that further refinement and optimization are necessary to improve the accuracy of the sensor. One proposed enhancement involves utilizing the zero method with active patterns in future work to achieve more precise information. Despite the current limitations, the sensor holds significant potential for various applications when combined with other devices. The use of transparent silicone rubber makes the sensor simple, cost-effective, and capable of high-resolution detection. The transparency also opens up possibilities for applications such as a contactless sensor or an interactive device, enhancing its practical implications. The research introduces a novel tactile sensing method that maximizes camera resolution and detects surface deformation through the optical lever principle. While the current implementation has room for improvement, the concept contributes to the development of cost-effective and versatile tactile sensors with potential applications in diverse fields. The simplicity and high resolution of the proposed sensor make it a valuable addition to the landscape of tactile sensing technologies.
