Researchers present a new method of wirelessly recharging medical device batteries with ultrasound
Human beings don't come with power sockets, but a growing numbers of us have medical implants that run off electricity. To keep our bionic body parts from powering down, a group of Arizona researchers is developing a safe, ...
TopoChip reveals the Braille code of cells
Cells in the human body change shape as they crawl, split, or cling to other surfaces, but while the scientific literature is filled with examples of how cell shapes shift in response to things they touch, little is known ...
Qualcomm's brain-inspired chip: Good phone, good robot
Improving the performance of titanium implants by bioactive composite coatings
Researchers in Japan and China tested a novel urease fabrication process for coating titanium implants with bioactive CaP/gelatin composites. Published in Science and Technology of Advanced Materials, the re ...
New nanotube surface promises dental implants that heal faster and fight infection
A brighter, better, longer-lasting dental implant may soon be on its way to your dentist's office.
Paralysis promises smart silk technology
(Phys.org) —Oxford University researchers have harnessed the natural defence mechanism of silkworms, which causes paralysis, in what is a major step towards the large-scale production of silks with tailor-made ...
New atomic crystal dynamic of the white pigment titanium dioxide discovered
Titanium dioxide is an inexpensive, yet versatile material. It is used as a pigment in wall paint, as a biocompatible coating in medical implants, as a catalyst in the chemical industry and as UV protection ...
Sticking power of plant polyphenols used in new coatings
A simple kitchen sink experiment helped Northwestern University researchers discover that green tea leaves not only can be used to steep a good cup of tea, but they make an excellent antibacterial coating, too.
New coating may help joint replacements bond better with bone
Broken bones and joint replacements may someday heal faster, thanks to an unusual coating for medical implants under development at The Ohio State University.
Elastic electronics: Stretchable gold conductor grows its own wires
Networks of spherical nanoparticles embedded in elastic materials may make the best stretchy conductors yet, engineering researchers at the University of Michigan have discovered.
New frontier for cybersecurity: your body
So far, the idea of hacking into medical devices has been limited to fiction and hacker demonstrations.
Giant 3-D printed bugs shed light on insect anatomy
Minute insects, from the Australian National Insect Collection, have been super sized by up to forty times using a novel 3D scanning system and printed using a state of the art 3D printer.
3D printing tiny batteries
(Phys.org) —3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, ...
The body electric: Researchers move closer to low-cost, implantable electronics
(Phys.org) —New technology under development at The Ohio State University is paving the way for low-cost electronic devices that work in direct contact with living tissue inside the body.
