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, including ...

Nanofiber coating prevents infections of prosthetic joints

In a proof-of-concept study with mice, scientists at The Johns Hopkins University show that a novel coating they made with antibiotic-releasing nanofibers has the potential to better prevent at least some serious bacterial ...

Graphene is thinnest known anti-corrosion coating

New research has established the "miracle material" called graphene as the world's thinnest known coating for protecting metals against corrosion. Their study on this potential new use of graphene appears in ACS Nano.

Stimulating sight: New retinal implant developed

(PhysOrg.com) -- Inspired by the success of cochlear implants that can restore hearing to some deaf people, researchers at MIT are working on a retinal implant that could one day help blind people regain a useful level of ...

New Material Mimics Bone To Create Better Biomedical Implants

(PhysOrg.com) -- A "metal foam" that has a similar elasticity to bone could mean a new generation of biomedical implants that would avoid bone rejection that often results from more rigid implant materials, such as titanium. ...

Implantable medical devices powered by the ear itself

Deep in the inner ear of mammals is a natural battery—a chamber filled with ions that produces an electrical potential to drive neural signals. In today's issue of the journal Nature Biotechnology, a team of researchers ...

Implantable Device Offers Continuous Cancer Monitoring

(PhysOrg.com) -- Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but offer only a snapshot of the tumor at a single moment in time.
