It is reported that the two key components of this microsystem are made of protein nanowires. As a “green” electronic material, it can be reproduced by microorganisms, thus avoiding the trouble of generating electronic waste.
This research indicates that future green electronic products made of sustainable biomaterials will have great potential, and these materials are more likely to interact with the human body or different environments.
Research Picture-1: Flexibility Protein nanowire device
The University’s Department of Electronic and Computer Engineering (ECE) Assistant Professor and Biomedical Engineering Professor Jun Yao, and Microbiology Distinguished Professor Derek R. Lovley, jointly led everyone to complete this research.
Research picture-2: more Functional Awareness Neuromorphic Interface
According to the Combat Capability Development Command of the U.S. Army Research Laboratory that funded this research, the research team is working to create a self-sustaining intelligent microsystem.
In the first study, Tianda Fu, a graduate student led by Professor Jun Yao, said: Exploring the feasibility of adding living functions to electronic products is an exciting new beginning. At the same time, they are also looking forward to seeing what the further developed version will look like.
Research Picture-3: Integration Wearable neuromorphic interface interface
Previously, the research team has discovered that it is possible to use an air generator based on protein nanowires (Air-Gen related research published on Nature in 2020), from the surrounding environment/humidity To generate electricity. Based on this, this type of equipment can continue to generate electricity in almost all environments on the planet.
In the same year, the laboratory research team led by Professor Jun Yao also reported another technological development in Nature Communications, that is, protein nanowires can be used to create what are called “memristors.” (Memristors) electronic devices-support analog brain calculations and process ultra-low electrical signals that match the amplitude of biological signals.
Research Picture-4: Yes Reconstructing the neuromorphic interface
The good news is that by combining the above two studies, it can create a new type of microsystem that can use electrons from Air-Gen and use it to drive protein nanowires. Sensors and circuits made of memristors.
Now, this set of electronic micro-systems can extract energy from the environment to support sensing and computing without the need for external energy sources such as batteries, and it has the “intelligence” and self-sustaining ability equivalent to living organisms. More importantly, the system is also made of environmentally friendly biological materials (protein nanowires extracted from bacteria).
