Powering the Climb with CapDrive™
You can’t conquer high-altitude terrain with heavy, inefficient gear. CapDrive™ is the world’s most efficient piezo driver architecture, engineered to deliver high-voltage performance without the weight or the power drain. It is the oxygen for your haptic system.
10x More Power Efficient.
By recycling the energy from the actuator’s capacitance with every click, CapDrive™ reduces power consumption by 90% compared to legacy piezo drivers. This efficiency allows manufacturers to implement high-definition haptics in battery-constrained devices without compromising on longevity.
4x Smaller PCB Footprint
Space is a premium luxury on modern PCBs. CapDrive™ delivers a highly integrated architecture that drastically reduces the overall solution size, consolidating a full haptic engine into an ultra-compact footprint. This design enables premium haptic feedback in even the smallest form factors.
Integrated Force Sensing
CapDrive™ reacts to user intent with the speed of a reflex. Thanks to an ultra-fast startup time, our drivers can remain in deep sleep mode to conserve energy and wake instantly to deliver feedback. This rapid transition from sleep to waveform output ensures zero perceptible latency, creating a seamless and natural user experience.
Legacy haptic motors create the foggy view on the left. They accelerate slowly and vibrate with a lack of focus that hides the details. This "muddy" feedback disconnects the user from the device.
To reveal the sharp definition on the right, you need piezo actuators driven by CapDrive™. Our technology delivers the precise high-voltage control required to stop and start the actuator instantly. This allows the piezo to render textures that are as crisp and distinct as a mountain peak in bright sunlight.
CapDriveTM Technology brings HD Haptic feedback and integrated force sensing to the smallest devices, while reducing the solution's power consumption.
