Heating elements in wearable products rely on PCBA and temperature control circuits to operate safely and efficiently. This article explains how power delivery, sensing, and protection logic integrate with heating elements, and why system-level design decisions directly affect heating stability, user comfort, and long-term reliability.

Heating performance in wearable products depends heavily on how heating element resistance is matched to battery voltage. This article explains the electrical relationship between resistance, current, and power in 7.4V and 12V systems, and how proper matching improves efficiency, safety, and long-term reliability in heated clothing.
