Exploring the advantages of new piezoelectric haptic actuators over ERM and LRA

Touchscreen user interfaces have become ubiquitous due to their distinct advantages over mechanical interfaces. For consumers, the interface is smooth and intuitive, and for industrial users, the sealed display avoids the intrusion of dust and moisture. But there are downsides to both types of users. For example, consumers may lose the convenience and satisfaction of […]
