Abstract
A substrate includes a plurality of force sensitive resistors, among which at least two force sensitive resistors connected in series forms a force sensing unit, wherein the first end of the force sensing unit applied with a first voltage, and the second end of the force sensing unit applied with a second voltage which is different from the first voltage; a readout signal line tapped between two adjacent force sensitive resistors connected in series; and the force sensitive resistors are made of piezoresistive material.
Claims14
A substrate, comprising:
- a plurality of force sensitive resistors, among which at least two force sensitive resistors connected in series form a force sensing unit, wherein a first end of the force sensing unit applied with a first voltage, and a second end of the force sensing unit applied with a second voltage which is different from the first voltage;
- and
- a readout signal line tapped between two adjacent force sensitive resistors connected in series, wherein the force sensitive resistors are made of piezoresistive material,
- the substrate further comprising a current sensor connected with the force sensing unit in series, wherein the current sensor configured to measure a current flowing through the force sensing unit and the readout signal line is configured to read a voltage at a connection between the two adjacent force sensitive resistors.
