- This piezoelectric device is said to work even on one-tenth of the total power consumed by present piezoelectric solutions
- User can experience piezo-based haptic feedback by using a plug and play development kit with this driver IC
Electronic devices can communicate with users using alerts. The conventional alert systems for the devices were based on listening and viewing text or sound. Many methods were introduced in the last decade to enhance feedback abilities of the device. Haptic feedback is one of the proposed solutions. Haptic feedback is the use of touch to communicate with users to provide responses to an action.
Boréas Technologies has recently added a new product to its flagship low-power piezoelectric driver IC series. This device is said to be equipped with a wafer-level chip-scale (WLCSP) version. This provides the user with a high-definition (HD) haptic feedback. The IC can target markets related to mobile and wearable consumer products.
It is based on CapDrive architecture technology
As stated by the company, the driver is packaged in a 2.1 x 2.2 x 0.6 mm size. This IC is said to consume one-tenth the power of its nearest piezoelectric competitor. The low power device is based on CapDrive technology. It is a scalable piezo driver architecture that provides the foundation to haptic chip development. The advantages of this architecture include energy efficiency, low heat dissipation, and fast response times.
Supports a wide range of piezoelectric haptic actuators using third-party libraries
The operating voltage of the device ranges from three Volts up to five Volts. The IC can deliver a startup time of less than up to 300 microseconds. This provides a system with a quick response time. The IC can also improve the real-time haptic performance of the system. The driver is said to support a wide range of piezoelectric haptic actuators using third party libraries.
For easy integration, the driver can be combined with a development kit. This plug and play kit provides the user with haptic feedback experience. The kit comes with an opensource code . This code can be altered according to the usage of the IC.This allows the integration of the driver IC with analysis softwares like MATLAB, Python etc.
Haptic feedback is a mode of communication rather than a specific technology or application. It’s nothing less than an entirely new way for machines and humans to communicate.
Packed with all these features, the BOS1901CW can be suitable for resource-constrained devices. This category of devices includes buttonless smartphones, smartwatches, game controllers, and other low battery-powered devices.
