Abstract: The invention of Solar heat pad for analgesia comprises a solar photovoltaic panel, solar charge controller, rechargeable lithium-ion battery, flexible carbon-fiber heating elements, digital temperature sensors, an embedded microcontroller and safety protection circuitry. The working mechanism begins with the photovoltaic panel converting sunlight into electrical energy, which is regulated by the charge controller and stored in the rechargeable battery. During use, the stored electrical energy is supplied to the carbon-fiber heating elements, which generate therapeutic heat. The temperature sensors continuously detect the pad temperature and transmit the readings to the microcontroller, which compares the measured temperature with the selected therapeutic temperature and automatically regulates the power supplied to the heating elements. When the predetermined temperature is reached, heating is reduced or controlled to maintain the desired level, while an unsafe temperature or fault condition triggers automatic shutdown through the safety circuit. The device provides controlled and safe heat therapy for pain relief and muscle relaxation with particular suitability for healthcare applications in remote areas where conventional electrical power availability is limited.
