High-Resolution Tactile Skin is an optical-based sensor system designed to mimic human touch by mapping surface deformations in real-time with high precision.
Current tactile sensors often lack the resolution and real-time capabilities necessary for applications requiring fine touch sensitivity, such as precision assembly or medical procedures.
The tactile skin consists of a soft elastomer layer containing embedded markers. A camera positioned beneath the skin captures the movement of these markers as they are pressed, allowing for detailed and rapid analysis of surface interactions.
The manufacturing process involves creating a soft elastomer layer with embedded markers and integrating it with an optical camera system. This requires precise fabrication techniques to ensure consistent marker placement and accurate sensor performance.
First, the elastomer is molded into the desired shape. Next, micro-markers are embedded within the material using lithographic or laser-based methods. Finally, a high-resolution camera is placed beneath the skin for real-time data capture.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking processes required for marker embedding.
