Force Sensor Extends Mobile Device Functionality

Groomed for use with mobile devices, Peratech’s DFA distributed force array (DFA) sensor uses the company’s proprietary quantum tunnelling composite (QTC) technology to provide an array of single-point sensors that can be used in conjunction with a position sensor to measure force and correlate it with position. The sensor’s variable input force allows for additional, or new, functionality, such as the ability to navigate device menus and perform other operations via single-finger touch. It also allows for correct haptic feedback when the force reaches a pre-selected activation point, a feature that obviates false touch situations.

 

In multi-touch applications, the DFA’s proportional force sensing feature can determine the ratio of forces between presses (i.e. harder press to left or right), which can have benefits in improved control, especially in gaming applications. Peratech claims its distributed force array sensors are customizable, cost effective, low power, and can unlock the next-generation in HMI experiences, enabling new gestures, simplified interfaces, and endless flexibility.
