1. A handheld focused extracorporeal shock wave therapy (f-ESWT) device, comprising:
a plurality of piezoelectric elements, wherein each piezoelectric element of the plurality of piezoelectric elements is configured to generate an individual shock wave;
a power supply circuit configured to output a first DC voltage and a second DC voltage, the first DC voltage is greater in magnitude than the second DC voltage;
a plurality of driver circuits, wherein each driver circuit of the plurality of driver circuits is configured to be connected to the power supply circuit and to a corresponding piezoelectric element of the plurality of piezoelectric elements, each driver circuit of the plurality of driver circuits including a switching element electronically configured to switch between an open state and a closed state,
wherein when the switching element of a corresponding driver circuit of the plurality of driver circuits is in the open state, the corresponding driver circuit applies the first DC voltage and the second DC voltage to the corresponding piezoelectric element of the plurality of piezoelectric elements to pre-charge the corresponding piezoelectric element with a DC pre-charge voltage having a first polarity, and
wherein when the switching element of the corresponding driver circuit of the plurality of driver circuits is in the closed state, the corresponding driver circuit applies only the second DC voltage to the pre-charged corresponding piezoelectric element of the plurality of piezoelectric elements to cause the corresponding pre-charged piezoelectric element to generate the individual shock wave, the second DC voltage having a second polarity that is opposite to the first polarity of the first DC voltage.
