Wearable battery-free active paper printed RFID tag with human-energy scavenger

The embodiment of wearable battery-free, active, paper printed RFID tags provided with energy scavenging capabilities is presented. In this research, extraction of electrical energy from human body movement is obtained by a piezoelectric energy scavenger powering up an active RFID tag module implemented on flexible organic substrate. The application dealt with hereafter testifies a promising approach useful for a vast variety of applications where wearable electronics is required.
