This paper demonstrates a wireless uncooled infrared (IR) detector based on a Lamb wave resonator with low detection limit. Wireless transmission is achieved by near-field electromagnetic coupling. The wireless IR detector shows a monotonic decrease in impedance magnitude and resonant frequency with the change of the power density of the IR irradiation from 0.01 mW/mm2 to 0.7 mW/mm2. The average responsivities...
