Design and Fabrication of a Solar Power System for an Active RFID Tag

Nji Raden Poespawati, Muhammad Rifki Nugroho


Abstract: An active Radio-Frequency Identification (RFID) tag is a low-power device, which is often
used as a tracking device, where operation of this tag will be in remote areas
from an electrical
power source.
Therefore, this device
requires an independent
power source. To meet these needs, solar
power may be used, which can be accessed anywhere there is sunlight. Supercapacitors (SC) are used as
an energy source to support a solar
power system. The advantage
of supercapacitors, as an
energy storage device, is their long
life cycle
that means more charging and discharging processes compared to a conventional battery. The
design and fabrication of a solar power system for an active RFID tag with supercapacitors as the energy
storage will be covered in this paper.
Keywords: Active RFID tag; Battery charging/discharging; Load regulator; Solar panel; Supercapacitor
