Patent number: 11841340Abstract: Electronic devices and methods for reading an output signal and controlling a three-electrode electro-chemical amperometric sensor include an operational amplifier having a non-inverting input adapted to receive a biasing electric potential and an inverting input connectable to a reference electrode of the sensor. The devices further include one or more MOS transistors connected to the operational amplifier, with a first MOS transistor connectable to the collector electrode of the sensor to receive or supply a MOS transistor channel current representative of the cell current generated in the sensor, and a second MOS transistor connectable to a reference voltage by a conductor or a resistor. The resistance is lower than the cell impedance such that the current in the second MOS transistor channel depends on the current in the first MOS transistor channel through a nonlinear gain dependent on the resistor.Type: GrantFiled: February 27, 2019Date of Patent: December 12, 2023Assignee: DISTRETTO TECNOLOGICO SICILIA MICRO E NANO SISTEMI S.C.A.R.L.Inventors: Giovanni Maira, Luigi Occhipinti, Bruno Giuseppe Pignataro, Vincenzo Vinciguerra

Patent number: 11630037Abstract: A particle sensing device is disclosed for sensing particles entrained in a gas, distribution of particle sizes including a first size range (e.g. PM2.5) and a second size range (e.g. PM10), larger than the first size range. A thermophoretic impulse is applied to the entrained particles. The device has a a first sensor, downstream of the thermophoretic impulse region. The thermophoretic impulse, the flow of gas and gravity combine to cause at least some of the particles to follow respective trajectories within the sampling volume. An interception unit is interposed between the thermophoretic impulse region and the first sensor, to intercept the respective trajectories of particles of the second size range but not respective trajectories of particles of the first size range. The first sensor is located to intercept and detect the respective trajectories of particles of the first size range.Type: GrantFiled: September 18, 2018Date of Patent: April 18, 2023Assignee: CambAir LtdInventors: Luigi Occhipinti, Pelumi Oluwasanya
