- The RFID (Radio-Frequency Identification) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. Some RFID tags have been used in severe environment of temperature ranged from 200°C to 250°C for a long time and may cause serious problems such as signal error, short life cycle and explosion. Conventionally, the RFID tags for high temperature applications consisted of Fe-alloy housing part, ceramic powder and RFID sensor. However, it has disadvantage of heavy weight, signal noise and heat shield capability. In this study, we newly applied the aluminum porous materials fabricated by polymer leaching process into RFID tags in order to improve heat shielding ability, and compared the properties of RFID tag inserted by aluminum porous with the conventional one.

Abstract

- The effect of light scattering layers (400 nm, TiO_2 particle) of 4 mum thickness on the dye-sensitized solar cell has been investigated with a 12 mum thickness of photo-anode (20 nm, TiO_2 particle). Two different structures of scattering layers (separated and back) were applied to investigate the light transmitting behaviors and solar cell properties. The light transmittance and cell efficiency significantly improved with inserting scattering layers. The back scattering layer structure had more effective transmitting behavior, but separated scattering layer (center: 2 mum, back: 2 mum) structure (9.83% of efficiency) showing higher efficiency (0.6%), short circuit current density (0.26 mA/cm2) and fill factor (0.02). The inserting separating two scattering layers improved the light harvesting, and relatively thin back scattering layer (2 mum of thickness) minimized interruption of ion diffusion in liquid electrolyte.
