Wearable device with fluid-based circuits and stretch-sensitive materials, and systems including the wearable device used in conjunction with a virtual-reality headset

A haptic device for providing haptic feedback to a user, comprising:

• a flexible substrate configured to be worn on a hand of the user;
• an elastomer layer, supported by the flexible substrate, comprising fluid-based actuators for providing fluidic haptic feedback to the user;
• a sensing layer, supported by the flexible substrate, comprising at least one of stretch-sensitive fluidic-based sensing circuits or stretch-sensitive non-fluidic-based sensing circuits that are (i) configured to generate a change in electric potential in response to being stretched upon movement of at least one of the hand or a finger of the user and (ii) coupled to one or more of the fluid-based actuators of the elastomer layer via an electrical-fluidic junction;
• and
• an electronic circuit configured to operate the fluid-based actuators of the elastomer layer.

A virtual reality system, comprising:

• a virtual reality headset configured to display a virtual object in a virtual reality environment, augmented reality environment, mixed reality environment, or a combination thereof,
• a haptic glove, comprising:
• an elastomer layer comprising fluid-based actuators for providing fluidic haptic feedback to a user of the virtual reality system;
• and
• a sensing layer comprising at least one of stretch-sensitive fluidic-based sensing circuits or stretch-sensitive non-fluidic-based sensing circuits that are (i) configured to generate a change in electric potential in response to being stretched upon movement of at least one of the hand or a finger of the user and (ii) coupled to one or more of the fluid-based actuators of the elastomer layer via an electrical-fluidic junction;
• and
• an electronic circuit configured to operate the fluid-based actuators of the elastomer layer of the haptic glove based on data provided by the virtual reality headset.
