1. **Introduction**

Temperature measurements are vital to our life and various activities. Temperature sensors are devices that measure the target temperature and convert it into an electrical signal. Many temperature sensors and measurement technologies have been developed and provided in industry and laboratories, including temperature probesused for immersion temperature measurement in liquids, air, gas, or wells in solid material, and surface sensors such as fast-response thermocouples mounted in a polyimide carrier for easily measuring surface temperatures or heat flux. Fiber optic monitors and fiber optic sensors have been designed to work more reliably than traditional sensors due to their resistance to outside influence such as microwaves, electromagnetic interference, and radio frequency interference. There are also non-contact temperature measurement solutions for remote measurement or human body temperature measurement. Recently, the smart temperature sensing has greatly advanced the applications such as pandemic mitigation, point-of-care healthcare, and harsh environment monitoring [1, 2].

There are many different types of temperature sensors, each with its own advantages and disadvantages [3, 4]. Some of the most common types of temperature sensors include:


The advanced applications of temperature sensing are constantly evolving. Some of the most exciting new applications include:
