Stretchable Broad Impedance Bandwidth RFID Tag Antenna

Introducing innovative stretchable RFID devices with a broad impedance bandwidth, addressing the critical limitations of existing RFID systems in environments with variable characteristics.

The Need

Current passive UHF RFID systems falter in environments with fluctuating pressure, stress, and temperature due to their sensitivity to antenna deformation caused by changes in dielectric constant. A pressing need exists for stretchable RFID devices capable of operating seamlessly in diverse conditions, providing reliable inventory tracking and item identification.

The Technology

Our stretchable RFID devices feature a flexible design with a broad impedance bandwidth. Consisting of an RFID chip and antenna, the device ensures electrical and mechanical stability even in dynamic environments. The RFID antenna incorporates end-loading bodies that surround orifices, allowing stretchability without compromising the device's performance.
