Researchers in Austria have developed a sock that adds sensation to prosthetic limbs.
Called proCover, the design of the sock is close to the natural sense of touch.
The wearable is a low cost one and this means more people can afford it. The sock covers the entire foot and ankle. This is in turn connected to a ring of vibrating motors that can be worn wherever the user finds convenient.
The motors vibrate at different frequencies depending on where the pressure is put.
