What Is 4D Sound?
ViviTouch 4D Sound was developed with EAP (Electroactive Polymers). Pioneered by Bayer, EAP is an incredibly thin and flexible film that can be used as a flexible capacitor. The proprietary dielectric polymer expands when exposed to an electrical current and contracts when electricity is discharged. Stretchable electrodes are printed on either sides of the EAP film. Furthermore, by printing a specific frame pattern, a developed planer actuator acts as a new type of electrical motor converting electrical energy directly into mechanical motion.
The printed film is designed into an overthe‐ear headphone, these polymer motors move the skin around the user’s ears and generates a very realistic subwoofer experience similar to what one would normally feel only in a concert hall or movie theatre. The electro-active polymer has 10x faster response time and covers a broad frequency range. 4D Sound can generate thousands of unique sensations and enables a full spectrum of sensory sound.
