Miniature insulated lead NTC thermistor produced by EXSENSE Electronics Technology Co., Ltd., has the characteristics of high precision (precision can up to ±0.5%, ±1%, ±2%, ±3%), great sensitivity, good stability, small size and so on. It is widely used in various medical equipment, wireless charging, physiotherapy equipment, etc.

In today's intelligent era, computers, mobile phones, televisions, tablet computers and other electronic devices have become a part of people's daily work and study, and watching screens for a long time has become a normal life. However, staring at the screen for a long time can cause eye fatigue and eye dried tears, which can cause or worsen myopia in severe cases. In order to protect the eyes and relax the eye, the intelligent eye massager came into being.

Intelligent eye massager on the market can release heat to relieve eye fatigue and relax the muscles around the eyes while massaging the eyes. In order to prevent scald caused by excessive temperature, miniature insulated lead NTC thermistor is usually added to the intelligent eye massage device for temperature monitoring and temperature controlling. The addition of NTC thermistor can well assist the work of eye massager to maintain the heat at the appropriate temperature point and improve the user experience.

Miniature insulated lead NTC thermistor, because their resistance value decreases with increasing temperature, and vice versa. Use of this characteristic, intelligent eye massager manufacturers will add a thermistor in the circuit board for temperature monitoring and controlling, real-time monitoring of the current hot compress operating temperature, and transmitted to the micro control unit, to stabilize the uniform heating temperature, so that the intelligent eye massager in operation process does not exceed the maximum temperature of 42~43℃, lest cause low temperature burns.
