Monitoring

Though the third generation of Oura's health-tracking ring was a much slicker wearable than its rather bulky first offering, a perfectly circular design has so far eluded the company... until now, with the launch of the Oura Ring Gen3 Horizon.

Amazfit kicked off the fourth generation of its GT series smartwatches earlier this year with the launch of the GTS 4 Mini, and has now added two more models at IFA 2022, which boast dual-band GPS supporting five satellite systems.

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from happening, using scattered light.

Amazfit has launched a new compact-but-powerful smartwatch called the GTS 4 Mini, which offers a 70 percent screen-to-body ratio, can go the distance with a 15-day per-charge battery, and comes with over a hundred activity tracking modes built in.

Scientists have developed a new electronic “tattoo” that can monitor a patient’s blood pressure continuously. The e-tattoo is made of graphene and can be worn for long periods without getting in the way, allowing for better health data.

Garmin has added solar charging to its latest Edge bike computer, which boasts up to 100 hours of per-charge battery life, improved GPS accuracy, more ride analytics, easy setup out of the box and a refreshed user interface.

Imagining a future where hundreds of sensors are placed around forests or farms for large-scale monitoring of the environment, scientists have developed platforms light enough to disperse like dandelion seeds in the breeze when dropped from a drone.

Healthcare workers often have to wear masks for up to 12 continuous hours, during which time they may become seriously exhausted. A new mask-mounted device is designed to help, by monitoring their vital signs and detecting leaks in the mask's seal.

Engineers from Yale University have developed a wearable device that can help individuals assess whether they have been exposed to SARS-CoV-2. The device clips onto a person’s clothes and capture aerosolized viral particles in the surrounding environment.

For people with coronary heart disease, regular monitoring of bloodstream cholesterol levels is essential – and it typically requires the drawing of blood samples. A new system, however, is claimed to provide the same data simply by imaging the skin of the hand.

A team of engineers has given microchips a new ability – the power of flight. Inspired by wind-dispersed seeds, these “microfliers” are shaped like tiny propellers to catch the wind, and may be the smallest flying structures ever made by humans.

Everyone responds to general anesthetics differently, which can make administering the correct dose tricky. A new device is designed to help, by continuously monitoring anesthetic levels in patients' bloodstreams during surgical procedures.
