These Tiny Magnetometers Detect Fields Generated by Human Heart!

How can i imagine this tiny and ‘poor’ little thing can help a human life? hmm… I’m still thinking.

At the National Institute of Standards and Technology (NIST) scientists have been working on microfabricated atomic magnetometers capable of detecting faint magnetic fields. The devices, about 1cm3 in size, were taken to the Physikalisch Technische Bundesanstalt (PTB) in Berlin, Germany where supposedly resides the most magnetically isolated building in the world. Using the tiny magnetometers, investigators were able to detect the magnetic signature of human heartbeats, perhaps opening up the possibility for a new modality to complement ECG.

Data-logging shirt for analyzing baseball biomechanics

The shirt was developed by Marcus Moche, Alexandra Morgan and David Schmidt as a Capstone Design Project—a senior-level team project that requires students to solve a “real-world” engineering problem or develop a viable product.

Pitchers become more susceptible to injury when they lose consistency in their mechanics—the physics of how they throw the baseball, pitch after pitch. After this, is going to be logged for analysis.

A company calling its collective group of body monitoring products the WIN Human Recorder system has released a new device called the HRS-I. Designed to measure and record a person’s electrocardiographic signals, body surface temperature and overall body movements, the tiny unit can easily be worn under your shirt as you attend to your daily business.

The device communicates wirelessly with a remote base and can last on a single charge for up to three days. Targeted toward companies working to monitor employee health, the HRS-I can be purchased for just 30,000 yen ($331) and the monitoring service costs just 10,000 yen ($110) per month.

AT&Ts Telehealth Wirelessly Monitors Patient Health

Sunday, January 18th, 2009




Doctors’ offices may soon become much less crowded. AT&T is developing a software tool and networking platform that will use wireless devices to record a patient’s health measurements at home and send the data to the doctor. AT&T’s system runs on both Wi-Fi — enabling videoconferencing — and a second wireless technology named ZigBee, which receives data from medical sensors. ZigBee consumes considerably less power than Wi-Fi, so monitoring devices, including thermometers, pill dispensers, blood-pressure monitors, and pulse oximeters, can use small batteries to transmit data over long periods of time.

Home-based monitoring services like AT&T’s — which is approaching the trial stage — could transform how doctors interact with their patients. “The health-care industry is under a lot of stress,” says Bob Miller, executive director of AT&T’s communications-technology research department, “so there’s a drive to explore ways of delivering better care at lower cost.” And greater convenience for both doctor and patient: If a physician notices, for instance, that a blood-pressure medication isn’t working, or if the patient isn’t taking the drugs regularly, she’ll be able to arrange a videoconference with the patient to discuss solutions.

A wireless retrofit for remote monitoring

Sunday, June 8th, 2008

Cambridge Consultants has demonstrated a one-chip platform called Vena which adds wireless technology to existing health monitors for just $10 per unit.

Vena includes support for both IEEE 11073 and the Bluetooth Medical Device Profile. Security is also built-in.

What we’re talking about is the use of unlicensed wireless frequencies, at short distances, to move data from a monitor to a PC and then, if necessary, out to the Internet.

I first wrote about this in 2003 as The World of Always On, and it is personally gratifying to see it come on-stream, especially as a retrofit.

As a retrofit, wireless technology should not need separate government approvals in each application. Once a device is approved, the retrofit is the mere transference of data.

This has tremendous potential in both critical care monitoring and wellness applications.

A real-time monitor with wireless capability could detect health attack precursors and order the ambulance before the patient was aware of symptoms.

In wellness, this would enable real-time tracking of workouts, catching “non-workout” exercise in, say, getting to and from the office, and detecting non-compliance with a coaching regimen.

Separately, but not coincidentally, Cambridge hired MIT Venture Mentor Craig Carlson to head its U.S. acquisition initiative. Read more…
