How do I configure a haptic button that works reliably?

Creating a piezo haptic button is not a trivial task. However, with the proper step-by-step approach, creating this device becomes more straight-forward.

Our application note on Solid-State Button Design details each step and provides guidance. Used in conjunction with Haptic Studio and Boréas development kits, creating a haptic button become much easier and the resulting configuration can be exported to be directly used in the SDK.

The application note covers the following topics:

• Mechanical and hardware design considerations

• Haptic Studio tool

• Evaluating the piezo actuator and usage range

• Waveform tuning

• Creating the button profile

• Porting the solution to your MCU/firmware

• IC performance optimization.
