Experimental skin tattoo accurately monitors blood pressure

June 27, 2022

A small temporary tattoo could be a promising and practical alternative to continuous monitoring of blood pressure, developed by researchers from the University of Texas at Austin and Texas A&M. The wearable health device is made from graphene, a material similar to the graphite rods inside pencils, and a durable, electrically conductive ink. Once printed […]

Tiny cleaning robots kill bacteria in tooth crevices

May 18, 2022

Miniaturised robots, or nanobots, are now being used by scientists at the Indian Institute of Science (IISc) to clean out bacteria hidden deep in our teeth. The helical-shaped nanobots are injected and steered within the tooth using magnetic fields, and can also be extracted out of the tooth once the heat-based deep cleaning task is […]

Charging pacemaker batteries with ultrasound

April 26, 2022

Scientists from the South Korean Institute of Science and Technology (KIST) are working on a noninvasive battery recharging system for heart pacemakers, which is a more convenient alternative to surgical replacement once a pacemaker’s battery loses charge. KIST’s implantable ultrasound-powered generator utilises “triboelectric” materials – when rubbed together, these materials produce an electric charge. In […]

New COVID-19 breath test reports over 90% accuracy

April 25, 2022

The US Food and Drug Administration (FDA) has granted an emergency use approval for a breath-based COVID-19 diagnostics test. The test device has successfully identified 91.2% of positive cases in a cohort of 2,500 subjects, according to a metric known as test sensitivity. The specificity of the test was even higher, as it correctly identified […]

Wearable device said to promote deep sleep

April 11, 2022

Researchers at ETH Zurich, Switzerland, have developed a mobile system, SleepLoop, that can aid deep sleep through auditory brain stimulation – essentially by playing precisely timed sounds through earphones to encourage sleeping. The device is unique because the wearer is not consciously aware of this sound. The SleepLoop system consists of a headband and bonnet […]

Successful 3D-printing of paracetamol in seconds

March 30, 2022

University College London (UCL) scientists have accomplished three-dimensional (3D)-printing of medicines in just 17 seconds as opposed to several minutes. A typical 3D printing process involves extruding resin layer-by-layer to form a structure – adding to this process, the UCL scientists used a vat photopolymerisation technique, whereby the resin contains dissolved drugs (paracetamol or acetaminophen) […]

HIFU treatment helps with gynaecological issues and preserves fertility

March 11, 2022

High-intensity focused ultrasound (HIFU) technology is a treatment for uterine fibroids and adenomyosis, both benign gynaecological tumours that diminish a woman’s reproductive health and chances of conception. Introduced at Mahkota Melaka Medical Centre (MMC) in Malaysia last August, HIFU offers a non-invasive and cost-friendly option for women with gynaecological issues, with clinically proven, positive outcomes. […]

Scientists develop a wearable UV sensor from light-sensitive squid pigment

March 2, 2022

A team from Northeastern University have created a dime-sized UV (ultraviolet light) detection sticker from a study into the colour-changing ways of camouflaging squid. Over the last decade there have been numerous technological advancements designed to reduce incidences of skin cancer due to UV exposure: a serendipitous discovery was made when Northeastern scientists noticed a […]

Human protein sensitivity increased with “sonogenetics” ultrasound stimulation

February 11, 2022

Scientists from California’s Salk Institute for Biological Studies have developed an ingenious method to safely activate, and control mammalian cells located deep in the body – by using “sonogenetics,” a burst of ultrasound. Sonogenetics was used to activate human cell lines in vitro and brain cells inside living mice, and so paves the way toward […]
