Pressure sensing method and system
2015
The present invention provides a method and kinds of pressure sensing system, which includes a difference △ resistance value R of the time before and after reading a stored resistance value R and calculated to obtain at least △ R / R after, according to at least △ R / R or a △ R / R and the preset value of at least the most matching database, obtaining at least △ R / R or more △ R / Fn R pressing force value corresponding to a sum, can accurately obtain the resistance value of the large deformation , effectively reducing the noise signal and the use of variance and prior values generated by operation method, material or structure without the need for pressure sensing electrode is particularly limited, it may also be achieved an efficient and precise detection of the pressure sensing and signal processing .
