Peratech has introduced a new force touch sensor for use with mobile devices. The distributed force array (DFA) sensor uses Peratech’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 (such as capacitive) to measure force and correlate it with position.   The DFA sensor’s variable input force allows for additional, or new, functionality, such as the ability to navigate device menus and p...
