Application: Systems, methods, and devices for haptic feedback (Patent ID: US20240212465A1)
The patent filed by TDK Corp describes a wearable device that includes a flexible substrate with microfluidic devices attached to it, each with an actuator to displace a portion of the substrate based on fluidic pressure. The device also includes a control module, a fluid reservoir, and fluidic connectors. The wearable device can be in the form of a glove with microfluidic devices corresponding to digits, generating a three-dimensional kinesthetic force pattern on the user's body.
The wearable device further includes a power system, with at least a portion arranged in a helical pattern around the user's body. The microfluidic devices can provide localized haptic feedback to the user and are controlled by a digital reality system through the control module. The device's substrate consists of multiple layers, including an impedance layer and filler layers to adjust stiffness, with a cantilever anchor to couple the layers. Each microfluidic device has inlet and outlet ports, electrodes for actuation, and the fluidic connectors can be made of carbon nanotubes.
