These Tiny Magnetometers Detect Fields Generated by Human Heart!

Sunday, October 24th, 2010


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.

Wireless and real-time health tracker

Tuesday, January 19th, 2010


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.

RFID making in roads in health care

Sunday, June 15th, 2008

tag_green_inhand.gifThe last thing a hospital employee wants to do is run around searching for a piece of equipment needed for a patient or an upcoming surgery. If the device can’t be found, often, hospitals rent the equipment even though it same device may be sitting somewhere in the hospital, such as a storage room or another area long vacated by the patient, unused. These rentals can cut into a hospital’s bottom line.

But using the same scenario, what if you could go to the nearest computer, call up the device number and get notification, within six feet, of where that device is? That’s the purpose behind RFID in a hospital environment. Yes, it’s the same technology used by major retailers or wholesalers to track products or shipments but health care facilities are also using it to save money.

Awarepoint, San Diego, Calif., was founded six-years ago to track assets and people in real time at acute care hospitals, says its CEO, Jason Howe. Like RFID, Awarepoint’s primary product, real time location service, has its own acronym, RTLS, which goes beyond location. “You also need to monitor and get history as well,” says Howe.

The company’s name is derived from this: “Find a point and you’re aware of everything,” says Howe. While Awarepoint is an active RFID company, he compares RTLS to an indoor positioning system. In fact, Awarepoint got its start by tracking kids at theme parks. RTLS grew from that when it was realized that such a system could work well in hospitals, which “have a lot of unique issues,” says Howe.

He describes what he calls five criteria that need to be in place to make RTLS advantageous for hospitals.

First, you need facility-wide coverage. “You have to cover every square inch of your medical facility,” says Howe. He likens this to GPS. If you drive outside a zone that may not be covered, there’s a problem.

Second, it has to be accurate enough to be able to pinpoint the item’s location. Is it in a hallway, outside of the hallway or in a room? “You have to have enough accuracy to tell you where things are,” he says.

Three, it has to be an easy to install. “You can’t afford to pull wires and cables everywhere. And you can’t shut down patient rooms or the operating rooms. You can’t interfere with any systems,” Howe says.

Lastly, you have to be interoperable with other systems in the hospital. “You have to be able to leverage those systems. There needs to be some way of integrating this system. It can’t be its own proprietary system.” (more…)
