Electronic Skins

Electronic skins represent a class of soft, ultrathin, and elastic sensor arrays capable of multimodal detection. Their unique form factor enables intimate, conformal lamination onto complex curvilinear surfaces, such as humanoid robotics to minimally invasive surgical instruments. Our group pioneers MEMS-compatible electronic skins utilizing 3D architectures. These 3D geometries expand mechanical degrees of freedom, thereby enabling the precise measurement of triaxial forces and complex tactile information. We innovate manufacturing processes to construct 3D structures across various scales, and apply these devices in biomedicine and robotics.
