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: A multi-gas analysis includes a semiconductor gas sensor driven by a constant resistance driver circuit with a driving current to obtain a sensing output of a gas in a gas sample. A processing unit is operable, based on a reference voltage from the constant resistance driver circuit associated with the driving current, in one of a gas-identification mode, where the gas is identified based on the sensing output obtained in response to fine variation of the operating temperature of the semiconductor gas sensor, and a gas-detection mode, where an analysis result indicative of the concentration of the gas is obtained based on the sensing output obtained in response to an optimal operating temperature of the semiconductor gas sensor.

Abstract: A portable NDIR breath acetone measurement apparatus includes a portable housing formed with an optical cavity, which is housed in a receiving chamber for containing a gas sample taken from an exhaled breath of a human subject. A control unit controls the temperature in the receiving chamber to a desired temperature, and controls an IR emitter disposed in the receiving chamber to stably emit IR spectrum radiation propagating along a zigzag path toward an IR detector, which is operated at the desired temperature to generate, in response to detection of the IR spectrum radiation, an IR signal that is processed and analyzed by a signal processing unit to obtain a measurement result indicative of the concentration of acetone gas contained in the gas sample.

Abstract: A microfluidic electroporation device for exogenous molecules transfection is disclosed. The microfluidic electroporation device includes an electroporation chamber assembly, an ultrasound vibrator, and a controller. The electroporation chamber assembly includes an input chamber for exogenous molecules, a MEMS filter, an activation chamber and a MEMS plate. The MEMS plate holds cells within individual cavity for electroporation. Both the MEMS filter and the MEMS plate are made of semiconductor process by wet etching and/or ICP dry etching with V-shaped cavities. The top surfaces of the MEMS filter and the MEMS plate are coated with metal layer for applying electric field during the electroporation process. The electroporation chamber assembly is attached to an ultrasound vibrator which is operated intermittently to allow cells to be fixed in the cavity of the MEMS plate during electroporation process and popped out for collection after electroporation process.

Abstract: A temperature sensing device includes a substrate, a first reflective module, a first window cover, and a dual thermopile sensor. The first reflective module is disposed on the substrate, including a first mirror chamber with a narrow field of view (FOV), and the first reflective module focuses a thermal radiation from measured object to a first image plane in the first mirror chamber. The first window cover is disposed on the first reflective module, and the first window cover allows a selected band of the thermal radiation to pass through. The dual thermopile sensor is disposed on the substrate and located in the first mirror chamber, and the dual thermopile sensor senses a temperature data from the first image plane. Additional second reflective module, LED source plus pin hole with same FOV of dual thermopile sensor can illuminate the measured object for ease of placement of object to be heated.

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.
