We are here to introduce the first Single chip pulsed ESR microsystem working at X-band frequencies and room temperature. The whole system is integrated in less than 1 mm^2.

We report on the design of a single-chip X-band pulsed ESR detector (0.7 mm²), and results of single pulse, Hahn echo, two echoes, Carr-Purcell, and inversion recovery echo measurements at room temperature. We measured 8×10⁷ spins/Hz^(1/2) spin sensitivity on a 0.1 nL sensitive volume, with <100 mW power consumption.
