Abstract: An infrared thermopile sensor includes a silicon cover having an infrared lens, an infrared sensing chip having duo-thermopile sensing elements, and a microcontroller chip calculating a temperature of an object. The components are in a stacked 3D package to decrease the size of the infrared thermopile sensor. The infrared sensing chip and the microcontroller chip have metal layers to shield the thermal radiation. To measure object temperature accurately under acute change in environmental temperature, this disclosure uses the duo-thermopile sensing elements, that one is the active unit for measuring the object temperature and another one is the dummy unit for compensating the effect from the package structure.

Abstract: An infrared thermopile sensor includes a silicon cover having an infrared lens, an infrared sensing chip having duo-thermopile sensing elements, and a microcontroller chip calculating a temperature of an object. The components are in a stacked 3D package to decrease the size of the infrared thermopile sensor. The infrared sensing chip and the microcontroller chip have metal layers to shield the thermal radiation. The conversion from wrist temperature to body core temperature uses detected ambient temperature and fixed humidity or imported humidity level to calculate the body core temperature based on experimental data and curve fitting. The skin temperature compensation can be set differently for different sex gender, different standard deviation of wrist temperature and external relative humidity reading.

Abstract: A thermal sensor package for earbuds includes two thermopile sensor elements on a single thermopile sensor chip, and the two thermopile sensor elements are separated by a block wall of a cap. One of the thermopile sensor elements senses external infrared thermal radiation through a window of the cap, and the other thermopile sensor element senses internal infrared thermal radiation from a package structure as a basis for correcting compensation. Therefore, the foregoing thermal sensor package for earbuds can quickly correct a measurement error caused by the package structure to improve the measurement accuracy. In addition, the forgoing thermal sensor package for earbuds has a simple packaging step and is easy to arrange a silicon based infrared lens to expand its application.
