Wearable ultrasound patch monitors blood pressure deep inside body

A new wearable ultrasound patch that non-invasively monitors blood pressure in arteries deep beneath the skin could help people detect cardiovascular problems earlier on and with greater precision. In tests, the patch performed as well as some clinical methods to measure blood pressure.

Enabling 'internet of photonic things' with miniature sensors

Whispering gallery mode resonators recorded real-time temperature data and, mounted on a drone, mapped temperature distribution.

Nano-sandwiching improves heat transfer, prevents overheating in nanoelectronics

Sandwiching two-dimensional materials used in nanoelectronic devices between their three-dimensional silicon bases and an ultrathin layer of aluminum oxide can significantly reduce the risk of component failure due to overheating.

Scaling up single-crystal graphene to over a foot long

The novel method, which produces a single layer of graphene, relies on harnessing a 'survival of the fittest' competition among graphene crystals.

Detecting hydrogen using the extraordinary hall effect in cobalt-palladium thin films

Researchers have conducted the first systematic study of hydrogen detection through Extraordinary Hall Effect in CoPd alloy thin films. The technique could improve hydrogen's safety and efficiency as a clean energy source.

A wearable device for regrowing hair

Researchers have developed a flexible, wearable photostimulator that speeds up hair growth in mice.

Scientists discover a 'tuneable' novel quantum state of matter

Scientists demonstrate quantum-level control of an exotic topological quantum magnet.
