What is the principle of car seat heating?

The principle of car seat heating is: a non-woven fabric with heating wires is arranged under the seat cushion. When the seat heating switch in the car is turned on, the heating wires are electrified, and the seat will generate heat, causing the seat to gradually warm up in a short time. This principle is somewhat similar to that of an electric blanket. A temperature sensor is installed in the electric heating pad to monitor the temperature changes of the seat, thereby controlling the power on and off of the heating wires to keep the seat heating temperature within an appropriate range. Seat heating is usually found in vehicles equipped with leather material seats. Since the surface material of leather seats tends to be cold in winter, with front seat heating, the seats won't feel like a cold leather chair during the freezing winter. Most electric heating devices have adjustable temperature functions.
I've been driving for twenty years, and the principle of seat heating is actually quite interesting. Inside the seat, there are heating elements like carbon fiber or resistance wires embedded. When current flows from the battery through these elements, heat is generated, warming the seat directly, much like an electric heater. The control unit manages temperature regulation to prevent burning you. In the past, we relied solely on the warm air from the AC in winter, but now, with just a press of a button, the seat warms up in seconds and is more fuel-efficient. However, it's important to avoid getting the seat wet, as it could cause a short circuit and damage the elements. Some new cars even allow App-controlled heating zones, making the design more user-friendly and long drives much more comfortable.
