Driving the Haptic
CapDrive™ technology platform is a proprietary patent pending scalable piezoelectric driver architecture on which Boréas’ haptic driver integrated circuits are based. CapDrive™ delivers the advantages of piezoelectric material to the user: greater energy efficiency, low heat dissipation and rapid response times, making CapDrive™ chips ideal for smartphones, wearables and gaming controllers in which size, power and thermal management are essential.
A piezoelectric haptic solution is composed of three elements: a microcontroller (MCU), a piezo driver and a piezo actuator.
The actuator is built with piezoelectric material (hence the name) that deforms when it receive a high-voltage electrical charge. When you control precisely the electrical charge, you can make the actuator vibrate and create haptic feedback. That’s where the piezo driver comes to play. The driver job is to take the microcontroller output and transform it into high-voltage electrical charge, so the actuator can create the desired haptic effect.
Boréas Technologies designs and commercializes innovative low power piezo drivers.
Our breakthrough CapDriveTM technology allows our piezo driver to:
Piezoelectric haptics can create high-definition feedback and improve dramatically the user experience. It’s now possible to integrate them in the smallest electronic devices that surrounds us thanks to our CapDriveTM technology.Learn More on CapDriveTM Technology
The word haptic, from greek ἁπτικός (haptikos), means “relating to the sense of touch” and comes from the Greek verb ἅπτεσθαι (haptesthai) which means “to touch.”
Touch is a powerful sense. In technology, haptic feedback is a way to transmit different information with vibrations, impulses or movements. This information can be added to smartphones, game controllers and every device using user interface.
Nowadays, high definition haptic feedback can create textures and transmit detailed information to the user. Thanks to our piezoelectric driver technology, system integrators can simultaneously implement high definition haptic feedback and reduce power consumption compared to other advanced technologies.
