Our Revolutionary Piezo Driver Architecture

Up to 10 Times More Power Efficient

Our BOS1901 haptic piezo driver is in a league of its own and can be up to 10 times more efficient depending on the application. Less power consumption also means less heat dissipation. Forget overheating problems. Perfect for power and space-limited devices like smartphones and wearables.

CapDriveTM Technology vs The Competition

CapDriveTM Technology is our exclusive patented, scalable high-voltage piezo driver architecture. It has been designed from the ground up, especially for piezoelectric haptic actuators. The ultimate goal was to offer the best performance and the lowest power consumption to unlock piezo actuators' full potential.

CapDriveTM Technology brings HD Haptic feedback and integrated force sensing to the smallest devices, while reducing the solution's power consumption.
