Abstract
This disclosure relates to systems and haptic actuators, and suitably haptic actuation resulting from the response to a magnetic field of magnetic particles within an elastomeric material. Such systems and haptic actuators are useful in structural materials, including as elements of wearables or accessories, as well as in other applications and devices where haptic feedback is desired.
Claims20
A system for providing haptic feedback to a user, comprising:
- a. an elastomeric material;
- b. magnetic particles dispersed in the elastomeric material;
- and
- c. an electromagnetic coil oriented so as to produce a magnetic field at the elastomeric material.
