A neuromorphic material mimics that of neurons in the brain, a goal of ours is to study and characterize a type of this material. Silica Nanosprings are used as a scaffolding for oxide semiconductors, conductive graphite, and magnetic nanoparticles to design neuromorphic devices. We use the memristive properties of oxide semiconductors, magnetic response of nanoparticles, and percolative pathways created by the nanospring junctions. We then search for spatiotemporal variations of the devices response which emulates the brain cell electrical activities.
The Setup
Our setup for measuring the electrical response of different neuromorphic materials.
Memristive Response
This image shows the resistive state bi-stability which means the device would take one state or the other depending upon its history of voltage if the previous voltage was high or low.
