Printed electronics open way for electrified tattoos and personalized biosensors

ScienceDaily.com: Nanotechnology News - 3 октября, 2019 - 15:32
Electrical engineers have devised a fully print-in-place technique for printable electronics that is gentle enough to work on delicate surfaces ranging from paper to human skin. This can be accomplished without additional steps to bake, wash or powder-coat materials. The advance could enable technologies such as high-adhesion, embedded electronic tattoos and bandages with patient-specific biosensors.

Liquid metal networks as an ideal platform for stretchable electronics

Nanowerk.com - 3 октября, 2019 - 14:58
A novel and very promising design strategy for stretchable electronics is based on liquid metals; specifically the use of the oxide shell of liquid gallium alloys to fabricate polymerized liquid metal networks (Poly-LMNs). The novel attribute of these Poly-LMNs is that they increase in conductivity as they are elongated, resulting in the measured resistance across the conductor remaining nearly unchanged as they are stretched to 700% their original length. The implication of this effect is that a circuit can now be designed with a stretchable Poly-LMN wire that won?t change its resistance when stretched.

Structural color printing of 3D microscale objects by shrinking photonic crystals

ScienceDaily.com: Nanotechnology News - 2 октября, 2019 - 17:28
Researchers have developed a 'coloring-by-shrinking' method to print arbitrary 3D microscopic objects exhibiting structural colors. The design consisted of woodpile photonic crystals with varying lattice constants as the 3D building blocks. These structures remain colorless until they are heat treated, causing them to shrink and manifest color, a result of their lattice constants shrinking down below the wavelength of visible light. The team printed a colorful microscopic Eiffel Tower with structural colors, demonstrating feature sizes smaller than 100 nm.
