Piezoelectric Haptic Feedback

Our high performance piezoelectric haptic actuators enable low power, thin, lightweight, and non-magnetic touch communication. As compared to traditional magnetic based haptic actuators, piezo.com's piezoelectric actuators can create a richer haptic experience. Our actuators are capable of single cycles, fast start-up, static deflection, and independent frequency, amplitude, and phase control capabilities – allowing the designer to control the feel, duration, and intensity of the sensation. The high performance and broad array of haptic feedback provided by our actuators are made robust and reliable by utilizing our packaging process. The packaging/sealing technology is enabling in wearable devices, automotive, medical, simulation and training [VR/AR/MR], industrial, and military applications where higher fidelity and survivability are of the utmost importance.

Evaluations and Testing:

Piezo.com, is capable of designing custom actuator sizes and form-factors to fit your application. However, for initial haptic evaluations, we recommend our S233-H5FR-1107XB and S128-H5FR-1107YB actuators. 

For haptic drivers, we recommend Boreas’ BOS-1921 high voltage piezo driver IC. The BOS-1921 is the most efficient and low power boost IC on the market. They also offer a development kit! For more recommendations and advice on how to drive our piezos, you can take a look at our blog
