Abstract: A flexible electric heating pad has a first laminate layer, a second laminate layer, and a printed layer formed on the first laminate layer. The printed layer includes a plurality of distributed conducting wires and a plurality of connected electric resistances. A circuit board is set at a contact point of positive and negative conducting wires of the printed layer. An electric wire connected to the circuit board can be plugged in a power supply terminal. An aluminum foil sheet is sandwiched between the laminate layers on an external exposed side of a surface of the printed layer.

Abstract: A custom heater for a hot compress pack includes a base, a temperature sensor, a lid and a power cord. The base includes a heating module configured in the base. The heating module includes a heat transfer wire of a heat conductor and a circuit board. The circuit board is connected to the heat transfer wire of the heat conductor by an electric wire. The temperature sensor switch is connected to the circuit board of the heating module by the electric wire. An inner part of the lid can be pivoted on the base. The power cord is connected with the circuit board.
