Summary of NEW PIEZOELECTRIC FILM HAPTIC ACTUATOR MADE FROM ELECTRO-ACTIVE POLYMER FILM
KEMET introduces a high-definition piezoelectric polymer film haptic actuator, a 150 µm thin, flexible solution that embeds directly into product surfaces to create localized tactile effects without shaking the device. Unlike traditional eccentric rotating mass (ERM) technology, this electro-active polymer film offers superior displacement, force, and response time for applications like AR/VR, medical devices, and smart buttons.
Parts used in the High-Definition Piezoelectric Film Haptic Actuator:
- Piezoelectric polymer film haptic actuator
- Electro-active polymer film
- Thin-film actuators
KEMET Introduces High-Definition Piezoelectric Film Haptic Actuator for Next Generation of User Interfaces
Thin-film actuators add haptic skin to any product surface to create localized, independent sensations at any frequency creating a wide range of tactile effects.
KEMET, part of the Yageo Group and leading global electronic components supplier, announces its innovative haptic solution: the piezoelectric polymer film haptic actuator. When embedded directly into a product’s surface, the actuator acts as haptic skin that provides localized bodily sensations and tactile effects unavailable with other haptic solutions currently in the market. KEMET film actuators enable design engineers to implement advanced haptic solutions with high-performance actuators in a broad spectrum of applications that include remote controls, smart buttons, medical devices, AR/VR, and anything in contact with hands, fingers, head, and lips.
While piezoelectric haptic solutions are found in many applications, they are often large and heavy, thus shaking the entire device. KEMET’s thin (150 µm), flexible and conformable haptic actuators are made from a proprietary, patent-protected paper-thin material, an electro-active polymer film, that enables piezoelectric effects to mimic the sense of touch.Unlike eccentric rotating mass (ERM) technology, which is often used in devices for haptic sensations, KEMET haptic actuators do not shake the entire device. KEMET’s lightweight piezoelectric polymer film actuators offer superior performance with a combination of displacement and force, as well as response time, thus offering high-definition haptic feedback.
