The raw Aloe Vera flower extract displays memristive behavior with high conductivity, capable of switching between different memory states with impressive On/Off ratio and cyclability. This could pave the way for designing solid-state herbal memristors using active molecules present in Aloe Vera flowers.
A raw Aloe Vera flower extract has been studied here to reveal memristive behavior. The extract solution shows two distinct conductivities in its as-prepared and chemically reduced states. The amount of current flowing through the extract solution can be increased by means of a phenomenon similar to dynamic doping and can also be switched between the two memorylike states for multiple cycles. An impressive On/Off ratio value and cyclability can be achieved, which may pave the way for designing a solid-state herbal memristor using the active molecule(s) present in the Aloe Vera flower to take more advantage of this natural gift.
