Abstract: A waveguide for tympanic thermometer formed by an elongate hollow member having substantially ellipsoidal shape truncated at both ends along its major axis direction. The waveguide is interposed between a tympanic membrane of which the temperature is to be measured and an infrared radiation sensor so as to guide the infrared radiation from the tympanic membrane to the sensor. Alternatively, the waveguide may also be a hollow member including an end portion having a gradually reduced inner diameter toward the side of sensor. The gradually reduced end portion is preferably of a truncated half ellipsoidal shape having a length between about 1/10 to about 1/3 of the distance from the sensor to the distal end of the waveguide.

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.

Abstract: An infrared temperature sensor comprises a thermopile sensing chip. The thermopile sensing chip includes a chip substrate, a thermopile sensing unit, a heater and a temperature sensing element. The thermopile sensing unit is disposed on the chip substrate, receives infrared thermal radiation from a target and outputs a corresponding infrared sensation signal. The heater is disposed on the chip substrate and used to heat the chip substrate to a working temperature. The temperature sensing element is disposed on the chip substrate, senses the working temperature of the chip substrate and outputs a corresponding working temperature signal. In operation, the infrared temperature sensor can maintain the thermopile sensing unit at the preset working temperature. Thereby, a single-point temperature calibration is sufficient to obtain more accurate measurement results in a broad environmental temperature range.
