New microprocessor for microprocessors
The miniaturization of electronic devices entails the need for adequate power supply to enable them to function. University of Illinois engineers have designed an exceptionally small battery that can power individual microprocessors, independent of external power.
The battery was created using 3D printing, namely holographic 3D lithography and 2D photolithography. The new technique provides greater control over the structure of the electrodes, making it easier to match the battery to the specific application. The new invention has a thickness of only 10 μm and provides a voltage of 0.5 mA sufficient to supply the LED.
Microchips can have many different uses, primarily in the Internet of Things hardware, but not only. It can be used in electronic refrigerators, light switches that communicate with each other by radio or even car keys.
