LRA
Timeline (last 90 days)
The Taptic Engine is a linear resonant actuator (LRA) that has faster response times and more precise positioning compared to older eccentric rotating mass motors (ERM).
The Android ecosystem uses a mix of LRA and ERM solutions; flagship models such as the Pixel and Galaxy S series have mostly upgraded to LRA, while mid-range and low-end devices still largely use ERM.
LRA drives a mass in high-speed reciprocating motion via an electromagnetic coil, with a response speed far faster than traditional ERM motors.
