Low Power Network for Wireless Body Sensors

As wearable devices multiply and gather ever more data about our bodies, the batteries and wireless networks they rely on can become strained. To give wearables a longer battery life and to allow gigabytes of data to be transmitted at the same time, researchers at the National University of Singapore have developed a new type […]

Blood Flow Measurement Using Tiny LED Catheter

Measuring blood flow is important during a variety of surgical procedures, as well as in intensive care settings. Typically, this is performed intermittently, so there’s not a lot of temporal detail in the readings. Now, a team of researchers at Flinders University in Australia has developed a proof-of-concept prototype vascular catheter that (Read more...)

Tiny Nanowire Probes Measure Intracellular Electrical Activity

Researchers at the University of Surrey and Harvard University have developed tiny nanoprobes that can measure electrical signals inside cells, such as neurons and cardiac cells. Unlike previous technology for intracellular electrophysiology, the nanoprobes cause minimal destruction to the cells, and could pave the way for human-machine interfaces (Read more...)

Low Cost Medical Devices for Low-Resource Regions: Interview with Prof. Saad Bhamla, Georgia Tech

Advances in medical technology continue apace, with sophisticated new medical devices and therapies becoming available on an ongoing basis. However, medical technology often comes at a premium, and for low-resource regions sometimes even relatively basic medical devices, such as hearing aids, are inaccessible because they are too expensive. Similar (Read more...)

BIOTRONIK Releases BIOMONITOR III Injectable Cardiac Monitor

BIOTRONIK is releasing a new version of its popular BIOMONITOR injectable cardiac monitor. The BIOMONITOR III is less than half the size of the BIOMONITOR 2, while offering much clearer signal quality. It is designed to be injected under the skin, where it can reside for weeks while continuously monitoring and recording the patient’s electric (Read more...)

Canon Releases Aplio a-series Budget Ultrasounds

Canon Medical is releasing a new line of ultrasounds, called the Aplio a-series. Presented at this year’s American Society of Echocardiography’s annual meeting, the Aplio a450 and Aplio a550 are designed to be competitively priced while offering multi-purpose advanced imaging, including cardiac imaging. Built with some features taken fr (Read more...)

Contrast Agent Uses Heart’s Electricity to Activate Itself

Imaging the heart for signs of disease is still quite rudimentary. While CT, ultrasound, and PET (positron-emission tomography) scanners generate impressive looking graphics, they’re a long way from giving doctors a true representation of the anatomy and function of the heart and nearby vasculature. Contrast agents are widely used to allow th (Read more...)

Stretchable E-Tattoo for Long-Term Heart Monitoring

Researchers at the University of Texas at Austin have developed a wearable heart monitor which can assess heart health over several days. The research team call the device an “e-tattoo” and claim that its stretchability makes it more comfortable and convenient to wear compared with previously developed devices. The device is the first s (Read more...)
