Abstract
A wearable body temperature control equipment using body's temperature regulation physiology and a small heat and cold generation device has been developed. Since thermal sensation is settled by core temperature, by heating and cooling directly blood through the neck, the equipment inflects core temperature most efficiently. The equipment is composed of Peltier elements, and a radiation mechanism combining a water-cooling tube and a radiator. It is regulated by an individually adaptive temperature control algorithm that learn the hygrothermal sense of each wearer. Performance evaluation and safety confirmation have been carried out through experimental use in both temperature-humidity control room and daily life environment. The developed equipment weighs 650g including a rechargeable battery, and consumes only one-tenth of electric power compared to conventional air-conditioner. It implements neck temperature control from 20℃ to 40℃, enabling to always carry a comfortable thermal environment.
