Revolutionizing Prosthetics: MiniTouch Device Senses Temperature for Amputees

In a groundbreaking development, researchers have created the MiniTouch device that allows prosthetic limbs to sense temperature. This innovation is a significant step towards restoring the spectrum of sensory experiences for individuals with amputations and improving their quality of life. The device integrates off-the-shelf electronics without requiring surgical intervention, making it readily accessible as an enhancement to existing commercial prosthetic limbs.

The MiniTouch device is a functional artificial limb that has been fitted with fingertip sensors to sense and respond to temperature just like a living hand. The device provides a realistic sense of hot and cold in the missing phantom hand by delivering thermal information directly into nerve areas on the amputee's residual limb, which their brain believes are part of their body.

Fabrizio Fidati, a 57-year-old transradial amputee who tested the device, found that sensations of hot and cold were actually more intense in his phantom hand than in his natural hand. The MiniTouch increased Fabrizio's ability to distinguish between real and prosthetic arms when blindfolded although his accuracy was higher with his intact hand.

The technology is a step towards prosthetic limbs that restore a full range of senses, improving both their usefulness and acceptance by those who wear them. The MiniTouch device has the potential to revolutionize how amputees interact with their environment and enhance their emotional connection to artificial limbs.
