Abstract:Whiskers are specialized hairs which some mammals such as sea lions,cats, rats etc. use to sense stimuli from their surrounding environment. In this project we will investigate weather such a whisker transducer can be fabricated using a 3D printer. Furthermore the device is to operate on the principle of capacitive sensing. As the methods from printing conductive materials are limited, the capacitance will be induced by interaction between a PCB and the printed whisker. The objective of the device is to be able to measure the point of contact force along the whisker. To do this the device would be able to measure 2-DOF and decouple the forces acting on the whisker in order to determine the contact location. In this paper the first prototype of the whisker structure is presented, along with a method of determining the capacitance generated by the electrode pattern on the PCB.
