We aim to develop a new kind of electromagnetic field sensor by combining the high metrological performance accessible thanks to the exaggerated Rydberg states properties with the high degree of control and tunability offered by cold atomic ensembles trapped in arrays of optical tweezers. We plan to probe EM-fields over a wide frequency range from few 100s of MHz to few THz, given by the frequency difference between neighboring Rydberg states, with a target sensitivity of about 10 mV/cm/Hz$^{1/2}$ and with a spatial resolution down to few tens of µm, corresponding to the distance between two optical tweezers. We also intend to study the possibility to perform spectral analysis by making each atomic ensemble sensitive to a specific frequency. In the poster I will present the principle of operation of the sensor, the current experimental status together with some envisioned applications and possible ways of improvements.
