Allows for more easily building tiny machines, biomedical sensors, optical computers, solar panels, and other devices — no complex clean room required; portable version planned.

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have created “bubble-pen lithography” — a device and technique to quickly, gently, and precisely use microbubbles to “write” using gold, silicon and other nanoparticles between 1 and 100 nanometers in size as “ink” on a surface.
The new technology is aimed at allowing researchers to more easily build tiny machines, biomedical sensors, optical computers, solar panels, and other devices.
A couple weeks ago Samsung affirmed its ongoing commitment to the digital health space with the release of the Bio-Processor. The Bio-Processor is a single, compact chip that is capable of measuring PPG, ECG, skin temperature, GSR, and body fat. While it’s already in mass production and anticipated to be found in devices soon, Samsung took some time during its CES press event to demonstrate the Bio-Processor’s power in a prototype device called the S-Patch.
