ERM actuators are the most widely used and cost-effective form of haptics, producing vibration through an off-center spinning mass. Ideal for handheld devices, game controllers, and simple alert systems, ERMs offer basic, strong tactile feedback and are easy to implement.

LRA actuators offer more precise, high-fidelity vibration feedback than ERMs by oscillating a magnetic mass linearly. They are commonly used in smartphones, wearables, and medical devices where short response time and tuned frequency performance are crucial.

Piezo haptic actuators offer ultra-fast, highly localized tactile feedback with minimal power consumption and compact size. Ideal for premium touch interfaces, automotive dashboards, and smart surfaces where vibration precision matters most.

VCAs provide direct linear motion and precise positional control, making them ideal for advanced haptics, optics, robotics, and audio systems. VCA haptics enable force feedback in high-end interfaces and applications requiring accuracy and speed.
