Special Seminar: Restoring Upper Limb Sensation and Function with Advanced Prosthesis Technologies
3:30pm - 4:30pm ET
Meeting ID: 951 4202 1459
Prosthetic limbs and brain-computer interfaces (BCI) can help restore movement after injury; however, the lack of tactile feedback can make grasping and manipulating objects difficult. A major step in developing closed-loop neuroprostheses is providing the sense of touch back to the user to improve sensorimotor function. To enable this, we developed an electronic dermis (e-dermis) fingertip tactile sensor for producing biomimetic spiking responses to capture nuanced touch information during grasping with a robotic limb.
We investigated the use of noninvasive stimulation modalities of peripheral nerves to provide sensory feedback and improve perception and prosthesis control to individuals with limb amputation using neuromorphic stimulation models. Going further, we also created sensations of artificial touch in an individual with spinal cord injury through direct brain stimulation with a BCI to enable perceptions of complex objects and improve retained tactile sensitivity in the hands. Building on the advancements in prosthetic limb technology, we will also discuss the benefits of long-term, unconstrained prosthesis use outside the laboratory. Collectively, our work explores the role of sensory stimulation and advanced prosthesis technologies for improving function for individuals living with sensorimotor deficits.
