Inkjet-printed liquid metal could lead to new wearable tech, soft robotics | KurzweilAI

Inkjet-printed liquid metal could lead to new wearable tech, soft robotics | KurzweilAI | Human and Technology | Scoop.it
Purdue University researchers have developed a potential manufacturing method called “mechanically sintered gallium-indium nanoparticles” that can inkjet-print flexible, stretchable conductors onto anything — including elastic materials and fabrics — and can mass-produce electronic circuits made of liquid-metal alloys for “soft robots” and flexible electronics.

The method uses ultrasound to break up liquid metal into nanoparticles in ethanol solvent to make ink that is compatible with inkjet printing.

Elastic technologies could make possible a new class of pliable robots and stretchable garments that people might wear to interact with computers or for therapeutic purposes.

“Liquid metal in its native form is not inkjet-able,” said Rebecca Kramer, an assistant professor of mechanical engineering at Purdue. “So what we do is create gallium-indium liquid metal nanoparticles that are small enough to pass through an inkjet nozzle.

“Sonicating [using ultrasound] liquid metal in a carrier solvent, such as ethanol, both creates the nanoparticles and disperses them in the solvent. Then we can print the ink onto any substrate. The ethanol evaporates away so we are just left with liquid metal nanoparticles on a surface.”

After printing, the nanoparticles must be rejoined by applying light pressure, which renders the material conductive. This step is necessary because the liquid-metal nanoparticles are initially coated with oxidized gallium, which acts as a skin that prevents electrical conductivity.

“But it’s a fragile skin, so when you apply pressure it breaks the skin and everything coalesces into one uniform film,” Kramer said. “We can do this either by stamping or by dragging something across the surface, such as the sharp edge of a silicon tip.”

Silverstone B-64 balloon still flying

The B-64 balloon launched at 06:51 GMT on July 12, 2014 from Silverstone (in the UK) is still in the air transmitting on 434.500 MHz using Contestia 64/1000 and APRS

On Saturday, October 3 Phil Heron MI0VIM reported decoding data while it was over the North Atlantic ocean, coming up to 6th time it would pass the United Kingdom on it's continuing journeys around the world.

B-64 was built by radio amateur Leo Bodnar M0XER, he made both the plastic foil envelope and the solar powered transmitter payload which weighs just 11 grams.
