Injecting Electronics into the Brain

Several years ago, a wireless brain sensor capable of being implanted was being tested at Brown University. A team at Harvard has been working on creating scaffolds of a mesh of nano wires sandwiched in between layers of organic polymers, allowing it to culture living cells, creating a kind of “cyborg” tissue. They have now […]

Superconducting Islands Amplify Photon Pressure

The ripple in space that we call a photon, or wave/particle of light, does have some mass, but it is so small that is almost zero. It normally takes millions of photons just to measure any impact at all. Joint research based in Finland shows that an island of superconductivity can amplify the ability to […]

3D Printing Graphene Aerogels

Aerogel, aka “frozen smoke” is a light, porous, nearly translucent, matrix of silica, made by removing the liquid part of a gel. Aerogels can also be made from metals and from carbon. Graphene versions of aerogel offer intriguing combinations of strength and electrical conductivity. Lawrence Livermore Laboratory is working on a process that uses 3D […]

Colloidal Camouflage

Cuttlefish dynamically change both the color and texture of their skin to create camouflage that matches the environment around them. A University of Nebraska research team is doing the same thing using colloids in a multilayered structure. When light hits the colloid layer, heat convection reassembles it to replicate the light pattern. This technique is […]

Printing Liquid Metal

Flexible conductors printed on elastic materials is possible using a liquid metal nanoparticle filled ink. A new class of metallic nanoparticles is likely to spawn breakthroughs in fields such as: soft robotics, conformable electronics, wireless communications, micro/nanofluidics, wearable/implantable devices, and energy storage and transport systems. Inkjet-printed liquid metal could bring wearable tech, soft robotics – […]

Nanoparticles Reverse Bone Loss in Mice

Silica nanoparticles not only suppress bone loss but also promote bone acretion. Silica Nanoparticles Partially Reverse Osteoporosis in Mice – [fightaging.org] At the small scale, bone structure is constantly remodeled throughout life. We lose bone mass and strength as we age, a condition known as osteoporosis, in part due to a systemic shift of the […]

Generic Re-programmable Electronic Circuits

It is possible to create flexible and controllable pathways of conduction by polarizing atoms. This means a single microchip or electronic circuit can be reprogrammed to accomplish different specialized functions. Perhaps someday soon, we’ll have a generic kind of electronics woven into everything we use. Electronic circuits with reconfigurable pathways closer to reality – [epfl.ch] […]

Microcapsules Target Arthritic Cartilage

Researchers at Queen Mary University of London have developed a new technique for delivering protein molecules to cartilage affected by osteoarthritis. When delivered in this manner, the protein (CNP) can reduce and possibly repair the damage caused by arthritic inflammation. New ‘microcapsules’ have potential to repair damage caused by osteoarthritis – [eurekalert.org] The researchers constructed […]

Recipe for Homemade Flexible Electronics

Combine pencil leads and dishwashing liquid, mix on high speed in a blender, pour the liquid into an ink cartridge and insert it into an ink-jet printer. Place a sheet of special fabric or plastic into the printer and print the circuit design onto it. Fold the printed sheet according to directions and connect it […]

From Samurai Swords to Smart Fabrics

Samurai swords were made in an elaborate, repetitive process that was ritualized to ensure the integrity of the methodology. A piece of iron was heated in a forge and folded and flattened many times to create layers of iron and carbon and iron oxide that were formed into swords with strength, flexibility and able to […]
