Aim at treating the disease such as hyperostosis and lumbar disc herniation, a convenient carrying and handling smart physiotherapy belt based on android system is designed in this paper. Its temperature and heating time could be controlled via bluetooth communication based on android system. Moreover, it could promote the blood circulation, relieve pain and improve disease with the use of medicine packet. With the power supple of the lithium polymer battery, it could control the heating by the PWM model of the MCU STC15W404AS. A kind of special charge and discharge circuit, which can be used as mobile power to intelligent devices, is presented in this paper to reduce the hardware cost and the waste of energy transmission. The experiment results show that the continuous heating system can work up to 8 hours with the purpose of physical therapy
