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: 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: 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 infant care apparatus includes a piezoelectric sensor and an infrared array sensor. The piezoelectric sensor senses a respiration rate and a heart rate of an infant. The infrared array sensor senses a body temperature and an occupancy state of the infant in a non-contact manner. The abovementioned infant care apparatus can assist in determining an abnormality of the respiration rate and the heart rate of the infant based on the occupancy state of the infant output by the infrared array sensor, so as to reduce a false alarm rate.
