Abstract
An array type pressure sensing apparatus suitable for multi-touch sensing and pressure quantification for gray scale identification is provided. The array type pressure sensing apparatus includes a plurality of first axes, a plurality of second axes, a plurality of piezoresistive units, a third axis, a plurality of standard resistors and a control unit. The second axes are disposed crisscross with the first axes, and there is one piezoresistive unit disposed on the cross between one first axis and one second axis. The third axis is disposed crisscross with the first axes, and there is one standard resistor on the cross between one first axis and the third axis. A pressure measurement method implemented using the array type pressure apparatus is also provided. The pressure measurement method is a gray scale identification method by pressure quantification of a linear piezoresistive system.
