摘要： An infrared thermal sensor for sensing infrared radiation is disclosed. The infrared thermal sensor comprises a substrate and a cap structure together forming a sealed cavity, a membrane arranged in said cavity for receiving infrared radiation (IR) through a window or aperture and a plurality of beams for suspending the membrane. At least one beam has a thermocouple arranged therein or thereon for measuring a temperature difference (ΔT) between the membrane and the substrate, the plurality of beams. Furthermore at least one beam is mechanically supporting the membrane without a thermocouple being present therein or thereon.

摘要： A thermal sensor device using a combination of thermopile and pyroelectric sensors is disclosed. The combination is achieved in a process flow that includes ferroelectric materials, which may be used as a pyroelectric sensor, and p-poly/n-poly for thermopiles. The combination retains the sensitivity and accuracy of the thermopile sensor and speed of pyroelectric sensors. The combination provides lower noise than individual thermopile sensors and results in a higher signal-to-noise ratio.

摘要： Infrared radiation fire detector, comprising a curved support surface and a plurality of infrared radiation sensors arranged on the support surface. Each sensor comprises a planar array of infrared radiation-sensitive elements, having a respective sight direction and a solid angle of view defined around the sight direction, which define a field of view associated to the sensor. The sight directions of the sensors intersect with one another at a central point and the sensors are spaced apart from one another by a given angular distance referred to the central point, the solid angles of view of the sensors having a same narrow width so that the fields of view of the sensors are non-intersecting with one another.

摘要： The present disclosure relates to a thermal sensor and a method for producing a thermal sensor of this type having a low signal-to-noise ratio at relatively high signal strengths. To this end, a thermoelectric generator is combined with a field effect transistor and a diode. Owing to its integrated diode and the barrier effect associated therewith, the thermal sensor is suitable for the economical and efficient design of imaging sensor arrays for converting thermal radiation into electrical signals.

摘要： In a composite sensor, an arrangement region of thermal image sensors and an arrangement region of range image sensors are arranged so as to overlap each other as seen in the mounting direction. This makes it possible to acquire thermal and range images coaxially, thereby suppressing image misalignment between the thermal and range images. In the composite sensor, a seal body formed by mounting the first and second substrates on top of each other seals a space about the thermal image sensors in a vacuum state. This can prevent the heat occurring about the range image sensors from affecting the thermal image sensor side. In addition, the substrate arranged with the thermal image sensors and the substrate arranged with the range image sensors are separate from each other, which can secure a degree of freedom in designing.

摘要： An IR sensor includes a suspended micro-platform having a support layer and a device layer disposed thereon. IR absorbers are disposed in or on the device layer. IR radiation received by the IR absorbers heats an on-platform junction of each of a plurality of series-connected thermoelectric devices operating in a Seebeck mode, the devices producing a voltage indicative of the received IR. Other thermoelectric devices are used to cool the platform, and a pressure sensing arrangement is used to detect loss of vacuum or pressure leaks.

摘要： An electronic apparatus includes a thermopile array sensor, a reflector, and a temperature detection unit. The thermopile array sensor includes a plurality of thermopile elements arranged in a two-dimensional array pattern and a temperature detection surface divided into a plurality of predetermined regions aligned in vertical and horizontal directions, and the thermopile elements output a temperature detection signal corresponding to a temperature of the respective predetermined regions. The reflector is set at an angle to reflect infrared light emitted from a measurement point located outside of a viewing angle of the thermopile array sensor, so as to allow the infrared light to be incident on the temperature detection surface. The temperature detection unit detects the temperature on the basis of the temperature detection signal outputted from each of the thermopile elements. The thermopile array sensor and the reflector are located inside the electronic apparatus.

摘要： An infrared sensor is formed in such a manner that an infrared receiver and a base substrate are spaced with a beam made of a thin-film phononic crystal in which through holes are arranged periodically. The beam made of a phononic crystal is formed in such a manner that a period P of through holes increases at arbitrary intervals in a direction from the infrared receiver toward the base substrate.

摘要： A dryer includes a cylinder, a heater, a motor, a temperature sensor and a controller. The heater heats air and delivers the heated air into the cylinder. The motor is used to drive the cylinder to rotate. The temperature sensor includes a thermopile array sensor and a signal processor. The thermopile array sensor is used to sense an infrared light radiated from clothing and output a sensing signal. The signal processor is used to process the sensing signal to obtain at least one of a temperature distribution uniformity and an average temperature of the clothing, and output a control signal according to the at least one of the temperature distribution uniformity and the average temperature of the clothing. The controller determines to stop the drying schedule according to the control signal. The above-mentioned dryer can stop the drying schedule automatically, so as to save energy.
