There are plenty of quality prosthetic limbs available on the market. Many of them lack tactile sensation and feedback. proCover is a prosthetic-sensing wearable that can be applied to lower-limb prosthetics to add tactile sensation and feedback.
ProCover is a wearable in the form of a textile sock (“made from one layer of piezoresistive fabric sandwiched by two layers of conductive zebra fabric”) with a vibration armband and measurement tools. The sole has 6 different sensing regions. Pressure values read from the sock are mapped with actuators in the armband. As you can see in the above video, this is an app-enhanced solution. Media Interaction Lab has more on this story.
