Like photosynthesis in plants: This CPU uses solar power to 'run computations' without the need for batteries
- Penn State researchers built a monolithic 3D chip that runs entirely off ambient light without leveraging a battery
- The chip stacks silicon photovoltaics, MoS₂/WSe₂ complementary logic, and graphene chemical sensors within ~50 nm of each other
- The development also opens the door for larger 2D circuits that incorporate some of the same design philosophy in the future
Research at Penn State university has come up with an interesting breakthrough in engineering, building out a compact integrated circuit that runs entirely off solar power.
The IC, which skips batteries altogether aims to run calculations and be able to sense chemicals in its vicinity by harvesting solar power available to it aims to do so by stacking everything monolithically versus splitting things up across different dies.
The move comes as engineers continue to grapple with the need for long-lasting and versatile IoT and edge computing systems, many of which are deployed in...
