[ad_1] Memristor-based sensing devices generate biological-like electrical signals that mimic those found in the brain for better computing. Sensory neurons are impressive in their ability to collect, integrate, and refine vast amounts of data. They are an efficient example of how both sensing and computing can be combined in the same computing unit. Though AI…
