Title: Biometric skin contact sensor and method of operating a biometric skin contact sensor
Inventor: HENRICUS DERCKX
IPC: G06V40/13
Filed: 2020-09-03
Abstract: Biometric skin contact sensor comprising an array of sensor pixels 100. Each pixel comprises: a capacitive sensing electrode 120 that accumulates charge in response to proximity of a conductive object, a reference capacitor 110 connected to the sensing electrode, a sense voltage-controlled impedance (VCI) 160, a bias VCI 140, a reset VCI 130, and a select VCI 150. The impedance of the VCIs is controlled by the voltage applied to a control terminal. The VCIs may be thin film transistors. The sense VCI control terminal is connected between the capacitive sensing electrode and the reference capacitor. The pixel is arranged such that when a select voltage 102 is applied to the pixel the voltage at the control terminal of the sense VCI indicates the proximity of the conductive object. Biasing circuitry comprising a one-way conduction path (a diode) from a bias voltage 145 to the control terminal of the sense VCI is provided so that current flows from the bias voltage towards the control terminal in response to the control terminal voltage dropping below a floor value, or in response to the voltage rising above a ceiling value. The reset VCI is controlled by voltage 101 which applies a known reference voltage to the reference capacitor, optionally by providing a short circuit across the capacitor. A supply voltage 155 and read-out channel 165 are also provided.
