Active wearable for thermal regulation using a stretchable pump embedded in a glove. We developed a wearable device illustrating active thermal regulation on the human body by integrating a stretchable pump and a flexible fluidic circuit in a textile glove. The scope of the device is to transport heat to a different part of the body (in this case, from forearm to hand) by circulating the liquid through a serpentine. The heat in our experiment is generated by a flexible-foil heater mounted on the forearm. This heater simulates the generation of heat by the human body (e.g., during intense physical activity). Thanks to its low mass (1g) and compliance, the pump can be sewn on the glove and does not interfere with the wrist movements. We used an infrared camera to map the temperature. The video shows that when the heater is on and the pump is off, the heater reaches an average steady state temperature of 45 °C. Once the pump is activated, it pushes cold liquid into the serpentine on the heater from one side (top side in the movie) and extracts hot liquid from the other side (bottom side in the movie). The hot liquid cools down when circulating through the cooling serpentine on the glove and is pumped back to the heater. As a consequence, the pump cools down the heater to an average temperature of 42 °C. Thanks to its low power consumption, the pump does not heat-up the fluid circulating through it.
