Abstract :
We present pentacene-based radio frequency identification (RFID) transponder circuitry, patterned entirely using flexible shadow-masks, and operating at RF frequencies greater than 1 MHz. The circuits, fabricated on glass substrates, were powered using near-field inductive coupling, and designed for operation without a rectification stage. 1-bit transponders made using this approach operated at RF frequencies of 125 kHz (a common RFID frequency), and well above 1 MHz, and exhibited sufficient amplitude modulation of the absorbed RF to be detected externally with peak-detection demodulation.
