Piezo.com - Garment and Wearable Smart Tactor Piezo Haptic Kit


Piezo.com Smart Tactor Kit Module

This module was designed by our partner Piezo.com.

Boréas Technologies Product: BOS1901 Piezo Haptic Driver

Application of this module: Garment and Wearables

Piezo.com smart tactor kit uses the BOS1901 piezo haptic driver with their own piezo bender. This hardware was built to facilitate the integration of piezo benders in haptic applications. The main use cases for the smart tactor kit are garment and wearable applications where haptic feedback to enhance situational awareness is needed.

  1. Up to 4 tactors can be safely driven to their maximum output from a standard PC USB port, which provides up to 500 mA of current. This limit can be increased to 16 tactors by using an externally powered USB Hub capable sourcing 2 A of current.
  2. Maximum current draw occurs when driving between 250Hz and 350Hz at full amplitude.
  3. Square wave output near maximum parameters may overload the piezo driver. It is recommended to use an amplitude of 0.75 or less when driving square waves between 250Hz and 350Hz.
  4. Data rate can be adjusted in software.
