Abstract: SENSORY TOUCH AND FORCE FEEDBACK SYSTEM FOR PROSTHETIC ARMS USING SILICON DIAPHRAGM-BASED TUBES Sensory touch and force feedback system (100) for prosthetic arms using silicon diaphragm-based tubes, according to some embodiments herein. The system (100) includes a Silicone Diaphragm (108), a Fluid-Filled Flexible Silicone Tube (110), and a Skin-Side Silicone Diaphragm (102_. The Silicone Diaphragm configured at Fingertip Side of prosthetic (104). The Silicone Diaphragm acts as a primary pressure-receiving surface when a user touches an object. The Fluid-Filled Flexible Silicone Tube is a long, narrow, highly flexible tube filled with an incompressible fluid that converts external touch or force into internal fluid displacement. The Skin-Side Silicone Diaphragm is a small silicone chamber or diaphragm placed on the user’s skin which expands outward when fluid pressure arrives to provide a tactile bulge or pressure feel to the user.
