(a) Schematic diagram for biological signal transmission in a biological synapse, and comparison to an Al/agarose@AuNPs/ITO memristive device. (b) Correlation between the PPF index and the time interval. The inset image is the conductance change triggered by a paired pulse. (c) Synaptic LTP and LTD results, stimulated by consecutive electrical spikes. (d) The energy consumption on the LTP and LTD processes. (e) Photographs of the agarose@AuNP film-based device subjected to bending from the flat, and LTP and LTD characteristics of the device up to 5000 bending cycles with a 4-mm radius of curvature.
