Abstract
Haptic actuators may include a first active material coupled to a first side of an inactive substrate and a second active material coupled to a second side of the inactive substrate. The inactive substrate may be formed to initially exhibit a nonplanar shape when the first active material and the second active material are not actuated. Various other methods, systems, and devices are also disclosed.
Claims20
A haptic actuator, comprising:
- a first active material coupled to a first side of an inactive substrate;
- and
- a second active material coupled to a second side of the inactive substrate,
- wherein the inactive substrate is formed to initially exhibit a nonplanar shape when the first active material and the second active material are not actuated.
1 more element
A haptic actuator, comprising:
- a plurality of distinct first active materials coupled to a first side of an inactive substrate;
- and
- at least one second active material coupled to a second side of the inactive substrate,
- wherein each first active material of the plurality of distinct first active materials is individually actuatable independent from other first active materials of the plurality of distinct first active materials.
1 more element
A wearable device, comprising:
- a body shaped and sized to be worn on a body part of a user;
- a haptic actuator coupled to the body, the haptic actuator comprising:
- an inactive substrate having a nonplanar shape when the haptic actuator is not actuated;
- at least one first active material coupled to a first side of the inactive substrate;
- and
- at least one second active material coupled to a second, opposite side of the inactive substrate.
