Abstract
A tactile sensor includes a pressure transducer encapsulated in an elastic material that defines a contact surface and provides a transmission path that transmits contact forces or pressure distributions applied to the contact surface to the pressure transducer. The pressure transducer can be enclosed in a protective housing that defines a chamber around the transducer. The housing can include one or more openings that expose the chamber to the exterior pressure. The tactile sensor can be made by applying the elastic material in liquid form and exposing the housing to a vacuum that removes air inside the chamber allowing the liquid elastic material to flow into the chamber. Once cured, the elastic material defines a contact surface of the tactile sensor and serves to transfer contact forces applied to the contact surface to the transducer.
