Designing next-generation optical antennas

Antennas catch radio waves, a form of electromagnetic radiation, from the air and convert the energy into electrical signals that feed modern telecommunications. They can also convert electrical signals into radio waves. ...

Electrical signals kick off flatworm regeneration

Unlike most multicellular animals, planarian flatworms can regrow all their body parts after they are removed. This makes them a good model for studying the phenomenon of tissue regeneration. They are also useful for exploring ...

Powering a pacemaker with a patient's heartbeat

Implantable pacemakers have without doubt altered modern medicine, saving countless lives by regulating heart rhythm. But they have one serious shortcoming: Their batteries last only five to 12 years, at which point they ...

Team develops optocoupler for spaceflight applications

Southwest Research Institute has developed a high-reliability, high-voltage optocoupler for spaceflight applications. NASA has selected the device as a power interface between the Europa Clipper spacecraft and three instruments ...

Waterproof graphene electronic circuits

Water molecules distort the electrical resistance of graphene, but a team of European researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, contact resistance is not ...

Artificial skin could give superhuman perception

A new type of sensor could lead to artificial skin that someday helps burn victims 'feel' and safeguards the rest of us, University of Connecticut researchers suggest in a forthcoming paper in Advanced Materials.

New optical memory cell achieves record data-storage density

Researchers have demonstrated a new technique that can store more optical data in a smaller space than was previously possible on-chip. This technique improves upon the phase-change optical memory cell, which uses light to ...
