Latest Patents

Moses holds a patent for a "Piezoceramic vibrotactile transducer based on pre-compressed arch." This invention describes the vibration and electrical characterization of a piezoelectric tactor actuator. The actuator is designed as a rectangular laminated flat plate, supported on two opposite sides while the other two sides remain free. Under axial compression from the supports, the plate deforms into a stressed shallow shell. By applying electrical high-frequency harmonic signals within relatively low-frequency bursts to the piezoelectric layers, the actuator demonstrates tunable capabilities. Depending on the axial compression and pre-deflection, as well as the frequency and magnitude of electrical input, the actuator can exhibit frequency/mode-controlled high-force vibrations over a large area, resulting in intense displacement jumps. A single-degree-of-freedom model and simplified 1-D models are also provided, showcasing the efficient conversion of electrical energy into mechanical energy.
