Piezo Haptic Computer Trackpad with BOS1901 Piezo Driver

O-film Computer Piezo Haptic Trackpad Module

Boréas Technologies Product: BOS1901 Piezo Haptic Driver

Application of this module: Computer Trackpad

This haptic computer trackpad module uses the BOS1901 driver with a piezo actuator. This hardware allows thinner, less complex, better performing and less power consuming trackpads than leading haptic trackpad currently on the market.

Piezo actuators can replicate with extremely high fidelity the tactile feeling of using a mechanical clicking trackpad. Our BOS1901 can also sense when pressure is apply to a piezo actuator, allowing both haptic feedback and pressure sensing capabilities from the same piezo actuator.

Let's see how the Piezo Haptic Trackpad Module compares to other technologies.

Trackpads with Piezo Haptics are Better

Different computer trackpad technologies comparison. Key advantages of the Piezo Haptic Computer Trackpad:

  • Lower Power Consumption
  • Thinner Solution
