Abstract: A method of sensing a temperature includes providing a voltage to reverse bias a PN junction of a junction diode. The PN junction has a junction capacitance. The method includes providing a reverse bias voltage change across the PN junction and detecting a value of the junction capacitance in response to the reverse bias voltage change. The value of the junction capacitance is a function of a temperature of the PN junction. An output signal is generated based on the detected junction capacitance, where the output signal indicates a temperature of an environment containing the junction diode.

Abstract: A device for measuring an electrical impedance of biologic tissue may include electrodes configured to contact the biologic tissue and generate a differential voltage thereon. The device may include a first circuit coupled to the electrodes and configured to force an oscillating input signal therethrough, and a differential amplitude modulation (AM) demodulator coupled to the plurality of electrodes. The differential AM demodulator may be configured to demodulate the differential voltage, and generate a base-band signal representative of the demodulated differential voltage. The device may further include an output circuit downstream from the differential AM demodulator and may be configured to generate an output signal representative of the electrical impedance as a function of the base-band signal.

Abstract: A gas measurement device measures gas using a gas sensor including a sense resistance exposed to the gas and a reference resistance not exposed to the gas. The gas measurement device applies a first current value and a second current value to the sensor. A detector functions to detect a first resistance variation and a second resistance variation of the sense resistance exposed to the gas with respect to the reference resistance as a function of the first current value and the second current value, respectively. The resistance variation dependent on relative humidity is then determined as a function of the first and second resistance variations and a first constant. The resistance variation dependent on gas content is then determined as a function of the first and second resistance variations and a second (different) constant.

Abstract: A thermographic sensor is proposed. The thermographic sensor includes a plurality of sensing elements each comprising at least one thermo-couple. The thermographic sensor is integrated on a semiconductor on insulator body that is patterned to define a grid suspended from a substrate; for each sensing element, the grid has a frame with the cold joint of the thermo-couple, a plate with the hot joint of the thermo-couple and one or more arms sustaining the plate from the frame. The frames include one or more conductive layers of thermally conductive material for thermally equalizing the cold joints with the substrate. Moreover, each sensing element may also include a processing circuit for the thermo-couple that is integrated on the corresponding frame. A thermographic device including the thermographic sensor and a corresponding signal processing circuit, and a system including one or more thermographic devices are also proposed.

Abstract: A sensing element integrated in a semiconductor material chip has a sensing diode of a junction type configured to be reverse biased so that its junction capacitance is sensitive to the local temperature. A reading stage is coupled to the sensing element for detecting variations of the junction capacitance of the sensing diode and outputting a reading acquisition signal proportional to the local temperature of the sensing diode. The sensing diode has a cathode terminal coupled to a biasing node and an anode terminal coupled to a first input of the reading stage. The biasing node receives a voltage positive with respect to the first input of the reading stage for keeping the sensing diode reverse biased.
