Monitoring Soft Shape Surface Deformation via Optical Images for the Distinction of Contact State

Soft-Touch Information Soft elastomer interfaces present an opportunity for capturing multimodal physical information. In article number 2300535, Xinming Li and co-workers realize the acquisition of soft-touch information through an optical sensing system, which can detect the surface deformation field by obtaining the irradiance of light of the contact area. The system design offers insights for contact state detection tasks and facilitates soft-touch sensing functions through the high precision of optical signal acquisition.
