Honey from bees could unlock the future of computing

Darling and computers don’t really go together well, but the researchers of Washington State University (WSU) think otherwise. WSU researchers built a proof of concept memory using natural honey of beekeeping origin.

A Memristor is an electrical component that limits or regulates the flow of electric current in a circuit and remembers the amount of charge that has previously passed through it. Memristors are important because they are non-volatile, meaning they retain memory without power.

The device featured training-free bipolar resistive switching, high switching speed of 100 ns set-up time and 500 ns reset time, peak moment-dependent plasticity and peak rate dependent plasticity learning behaviors and dissolving in water.

The study found that honey-based memristive synaptic devices show promise for advanced neural network implementation in green electronics and biodegradable neuromorphic systems. The researchers noted that future neuromorphic architectures would require that hardware devices not only be able to emulate fundamental functionalities of the biological synapse, but also be biodegradable to meet today’s ecological challenges of e-waste.

What is meant by neuromorphic computing?

Neuromorphic Computing is a method of computer engineering in which the elements of a computer are modeled after the systems of the human brain and nervous system. The term refers to the design of hardware and software computing elements.

The team published their findings in an issue of the Journal of Physics D: Applied Physics.
