    • Disclosed herein is a high-voltage generation apparatus using a piezoelectric transformer. The apparatus includes a power amplification unit for generating a driving voltage having a driving frequency, and amplifying and outputting the driving voltage. A piezoelectric transformer boosts the driving voltage unit depending on the driving frequency. An antenna is installed between an input terminal and an output terminal of the piezoelectric transformer and disposed on a bottom of a PCB, the antenna sensing a current depending on an output voltage of the piezoelectric transformer. A positive feedback loop feeds back voltage depending on output current of the piezoelectric transformer. An inverting amplification unit inversely amplifies an output voltage of the positive feedback loop. A first output voltage generation unit generates and outputs a first voltage.

    • The invention provides a piezo-electric tag (10, 300) in the form of a card, the tag (10, 300) incorporating a first dipole antenna (20), a first rectification circuit (30), a piezo-electric transformer (40), a second rectification circuit (50) and a transponder circuit (60). In operation, the antenna (20) receives incoming radiation and generates a corresponding signal Sa which propagates to the first circuit (30) which demodulates and filters it to generate a signal Sb. The signal Sb is applied to the transformer (40) to excite it. The transformer (40) increases the voltage amplitude of the signal Sb by generating a relatively higher voltage amplitude signal Sc which is used in the tag (10, 300) to generate a signal Sd for supplying power to the transponder (60). The transformer (40) provides voltage magnitude enhancement to generate potentials suitable for operating active electronic circuits incorporated into the tag (10, 300). The tag can be personnel wearable and even adapted for permanent inclusion into biological systems.
