Abstract
A counting device and a pedometer device is described. The counting device includes: a piezoelectric sensor generating a voltage signal when pressed; a rectifier receiving the voltage signal and rectifying the voltage signal to produce a trigger signal; a non-volatile counter receiving the trigger signal, and including a plurality of non-volatile D flip-flops counting according to the trigger signal and storing count data; a processing module reading the count data and using the count data to generate a counting value; and a wireless communication module transmitting the counting value to an external device. The counting device is powered with electrical energy of the voltage signal generated by the piezoelectric sensor.
