Summary
Penn State researchers built a bio-hybrid memristor that stores and processes data in the same place, cutting power use by 100x versus conventional memory approaches aimed at AI computing.
Synthetic DNA was combined with perovskite semiconductor films and doped with silver nanoparticles, letting the DNA conduct electricity and form ordered pathways for current flow.
Less than 0.1 volt was enough to move electrons reliably, while the device stayed stable at nearly 250 degrees Fahrenheit and remained functional at room temperature for more than six weeks.
The team said the DNA-perovskite combination delivered higher storage density than traditional devices and could support neuromorphic systems that handle complex workloads with far lower energy demand.
A patent application has been filed, and the researchers plan to further improve the technology for broader bio-inspired electronics uses.
