The use of ERM vibration motors in personal electronic devices was first pioneered by Motorola in 1984 with the introduction of this feature in their BPR-2000 and OPTRX pagers. Today there are alternatives such as linear resonant actuators LRA, which offer high reliability in a very small package size. These are typically used as actuators in haptic feedback applications and for basic vibration alert functions.
