Tiny Thermoelectric Device Restores Thermal Perception in Phantom Limb

Researchers created a revolutionary tiny and efficient thermoelectric device, which can help amputees feel temperature with their phantom limbs. Known as the wearable thin-film thermoelectric cooler (TFTEC), this device is lightweight, incredibly fast, and energy-efficient, potentially revolutionizing applications such as prosthetics, augmented reality haptics, and thermally-modulated therapeutics.
