Piezo haptic engines for laptop trackpads  


Enhanced user experience

The integration of haptic feedback into trackpads is emerging as a noteworthy trend, significantly improving the user experience. Leading laptop manufacturers are increasingly incorporating haptic technology into their premium product lines. When it comes to haptic engines, two prevalent options are the Linear Resonance Actuator (LRA) and the Piezoelectric engine. The latter, driven by piezoelectric elements, presents several distinct advantages over electromagnetic LRAs. These advantages include a faster response time, a slimmer profile, and greater efficiency. However, it’s worth noting that the implementation of a piezoelectric haptic engine on a trackpad still comes with a relatively high cost, albeit its remarkable performance benefits.


Dragonfly™ Haptic Curve

The Dragonfly™ Haptic Curve expertly combines cost-effectiveness with reliability, facilitating effortless integration. Thanks to its curved design and electrodes at both ends, it easily fits onto a PCB, simplifying electrical connections without the need for intricate FPCs or soldering. Impressively, while traditional configurations often demand four actuators at each corner, the Dragonfly™’s exceptional potency allows for a single central actuator, a feature that empowers laptop manufacturers to markedly decrease the expenses associated with implementing haptic trackpads.
