Vibromotor

A vibromotor is a small motor that produces vibration, commonly used in haptic feedback devices, smartphones, and wearable technology. The most common types are eccentric rotating mass (ERM) motors, which spin an off-center weight, and linear resonant actuators (LRAs), which move a mass back and forth. In accessibility applications, vibromotors are used in wristbands, gloves, and other wearable devices to provide directional guidance, notifications, and spatial information to blind and visually impaired users through patterns of vibration on the skin.
