Abstract: The disclosed haptic feedback system may include an actuator, a supply valve coupled to the actuator, an exhaust valve, and a fluidic mass controller communicatively coupled to the supply valve and the exhaust valve. The fluidic mass controller may (1) place the exhaust valve in a state that prevents a fluid from escaping the actuator, (2) activate the supply valve to fill the actuator with an amount of the fluid, (3) determine that the actuator has filled with the amount of the fluid, and then in response to that determination, (4) deactivate the supply valve to trap the amount of the fluid in the actuator. Various other apparatuses, methods, and systems are also disclosed.

Abstract: Methods, systems, and devices for sensing biometric signals and sending haptic precursors to effectuate a haptic sensation is disclosed. Utilizing a component, for example a sensing component or electrode, on a wearable device, a biometric signal of a user can be sensed. One or more haptic precursors can also be sent by the component to one or more targeted biophysical areas of the user. The one or more haptic precursors can cause the user to sense one or more haptic sensations at the targeted biophysical areas.
