Piezo Haptic Feedback Devices

PUI Audio's Haptics Phase 3 launch introduces piezo-based actuators, complementing their existing electromagnetic offerings. Innovations in piezoelectric materials and manufacturing processes have driven significant growth opportunities for piezoelectric haptic actuators. Various applications can achieve higher displacement precision, faster response speed, more significant generating force, and longer life to improve user experience. Piezoelectric material can produce a small voltage when impacted by a mechanical force. If this is reversed, and a voltage is applied to the material, physical motion is produced. This reverse piezoelectric effect is the fundamental principle behind using piezoelectric actuators to produce haptic feedback. Various voltage levels and driving signal patterns can cause a wide range of precise motion in the actuator; the resulting displacement can activate switches, create sound, release fluid, auto-break or auto-focus, and more. Typical applications include smart displays, touchscreens, wearables, IoT devices, human-machine interfaces, health monitoring and diagnostic devices, medical imaging, minimally invasive surgery, micropumps, experiential learning, AR/VR, gaming controls, and precision motion controls. These new devices are perfect when precise control and movement are required in a compact, thin profile with a unique sense of touch for high-quality tactile effects.
