Musical sensor shows bad medicine plays false note

Musical sensor shows bad medicine plays false note
What if a single musical note could mean the difference between life and death? A new sensor based on a 3,000 year old African musical instrument can be used to identify substances, including a poisonous chemical sometimes mistakenly added to medicines. The mbira sensor, which can be constructed from off-the-shelf or discarded materials, could offer pharmacists and consumers in the developing world inexpensive protection from counterfeit and adulterated drugs.

Ultrasound patch monitors blood pressure deep inside body

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. Applications include real-time, continuous monitoring of blood pressure changes in patients with heart or lung disease, as well as patients who are critically ill or undergoing surgery.

Breathing sensor for neonatal patients cleared by the FDA

Breathing sensor for neonatal patients cleared by the FDA
Masimo has announced FDA clearance of RAS-45, an acoustic respiration sensor for rainbow Acoustic Monitoring (RAM), for infant and neonatal patients. RAM could previously be used to monitor adult and pediatric patients greater than 10kg using RAS-125c and RAS-45 sensors. With clearance of the RAS-45 sensor for infant and neonatal patients, acoustic respiration rate measurement is now, for the first time, possible for patients of all sizes, including neonates, in the United States.

The next-gen of sensors and MEMS: what does the future look like?

The next-gen of sensors and MEMS: what does the future look like?
A new momentum from sensor makers responds today to the challenge of global healthcare transformation. According to Jérôme Mouly, Senior Technology & Market Analyst at Yole Développement, these innovations open the door to new business opportunities for mobile healthcare and emerging non-invasive devices.

Using biosensors to deliver personalised doses of antibiotics

Using biosensors to deliver personalised doses of antibiotics
A team of eight EPFL students has come up with a portable biosensor that can measure the amount of vancomycin in a patient’s blood stream, enabling doctors to better control the dosage and reduce harmful side effects. Their technology – developed for the upcoming SensUs international competition – could eventually be used for other antibiotics as well. At EPFL’s Discovery Learning Labs (DLL) – educational facilities designed to promote cross-disciplinary research – a groundbreaking new device is in the works.

Nerve gas detector built with Lego bricks and a smartphone

Nerve gas detector built with Lego bricks and a smartphone
Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders and scientists in the field identify deadly and difficult-to-detect nerve agents such as VX and sarin.

In-body GPS could track tumours or even dispense drugs

In-body GPS could track tumours or even dispense drugs
Investigating inside the human body often requires cutting open a patient or swallowing long tubes with built-in cameras. But what if physicians could get a better glimpse in a less expensive, invasive, and time-consuming manner? A team from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) led by Professor Dina Katabi is working on doing exactly that with an 'in-body GPS' system dubbed ReMix.

Yeast-powered radiation detectors may keep clinicians safe

Yeast-powered radiation detectors may keep clinicians safe
The same way that yeast yields beer and bread can help hospital lab workers better track their daily radiation exposure, enabling a faster assessment of tissue damage that could lead to cancer. But rather than building portable cellars or ovens, Purdue University researchers have engineered yeast 'microbreweries' within disposable badges made of freezer paper, aluminium and tape. Simply adding a drop of water activates the yeast to show radiation exposure as read by an electronic device.

Sensor helps doctors select effective cancer therapy

Sensor helps doctors select effective cancer therapy
MIT chemical engineers have developed a new sensor that lets them see inside cancer cells and determine whether the cells are responding to a particular type of chemotherapy drug. The sensors, which detect hydrogen peroxide inside human cells, could help researchers identify new cancer drugs that boost levels of hydrogen peroxide, which induces programmed cell death. The sensors could also be adapted to screen individual patients’ tumours to predict whether such drugs would be effective against them.

Integrated sensor could monitor brain aneurysm treatment

Integrated sensor could monitor brain aneurysm treatment
Implantation of a stent-like flow diverter can offer one option for less invasive treatment of brain aneurysms – bulges in blood vessels – but the procedure requires frequent monitoring while the vessels heal. Now, a multi-university research team has demonstrated proof-of-concept for a highly flexible and stretchable sensor that could be integrated with the flow diverter to monitor hemodynamics in a blood vessel without costly diagnostic procedures.
