Experimental Demonstration of In‐Memory Computing in a Ferrofluid System (Adv. Mater. 23/2023)

In-Memory Computing In article number 2211406, Alessandro Chiolerio and co-workers report that an Fe3O4 water-based ferrofluid can perform electrical analogue computing be programmed using quasi-direct-current (DC) signals read at radio-frequency (RF) mode. The colloid is capable of classifying digits 8 × pixel dataset through physical reservoir by training a readout layer.
