Abstract

一种压力感应系统及压力感应设定方法，压力感应系统（100）包括：第一压力感测片（10）、第二压力感测片（20）及处理装置（30），第一压力感测片的第一可挠基板（11）设有第一导电图腾（12）；第二压力感测片的第二可挠基板（21）设有第二导电图腾（22），第二压力感测片以第二导电图腾叠合于第一压力感测片的第一导电图腾；处理装置输出一个电力至第一压力感测片，并由第二压力感测片取得一个压力感测信号，并将压力感测信号与一临界值比较，以判断第一压力感测片及第二压力感测片是否受外力抵压；压力感应设定方法使用压力感应系统执行。通过临界值的判断，能避免误差信号的产生，进而增加测量精确度。
