Innovative Wearable Device Delivers Complex Sensory Feedback

Northwestern University engineers develop a haptic patch to enhance sensory experiences for gaming, VR, and healthcare.

The device uses a hexagonal array of 19 actuators to provide realistic touch sensations through the skin.
Applications include aiding visually impaired individuals and enhancing prosthetic limb feedback.
Developed by John A. Rogers and team, the patch builds on previous 'epidermal VR' technology.
Energy-efficient design leverages skin-stored energy, allowing longer operation on a single charge.
Blindfolded tests show the device effectively substitutes visual information with tactile feedback.
