postheadericon How-To: Fingertip heart rate monitor

DIY Heart Rate Monitor

Here’s a well-documented and rather enlightening project from Embedded Lab:

This project demonstrates a technique to measure the heart rate by sensing the change in blood volume in a finger artery while the heart is pumping the blood. It consists of an infrared LED that transmits an IR signal through the fingertip of the subject, a part of which is reflected by the blood cells. The reflected signal is detected by a photo diode sensor. The changing blood volume with heartbeat results in a train of pulses at the output of the photo diode.

postheadericon iPhonECG case monitors your heart rate to make sure you’re appropriately excited about CES

CES isn’t just about incrementally thinner or faster hardware, you know. Some people like to bring legitimately innovative ideas to the show, such as this iPhonECG case, which does what its name suggests: it takes an ECG (electrocardiogram) reading of your heart’s activity through a pair of electrodes and then communicates its findings to an iPhone 4 it can be attached to. We say it can be attached to an iPhone as communication is done wirelessly, so you’ll probably be able to monitor your ticker’s rhythm without the Applephone pressed against your bosom. Then again, maybe you like that. It’s a free world, we don’t judge. We’ll be sending out our most hairy-chested editor to give this thing a proper test at the Las Vegas convention next week. Until then, scope out the video after the break.

postheadericon Heart Spark pendant blinks with your heart, automatically gets you into B.E.D. (video)

Not that we haven’t been inundated with circuit-related fashion accessories in the past, but if you’ve already started thinking about what to get that lovely lad (or lady) in your life come February, look no further. SenseBridge, a research group with loads of passion, has just revealed the Heart Spark ($69, on sale now) — a wearable pendant with an integrated wireless receiver, a smattering of LEDs and a wow factor that’s downright heartwarming. The fortunate wearer must also strap a belt around their chest in order to monitor their heart rate, which is then transmitted wirelessly to the Heart Spark; upon receiving the information, the onboard lights will flash at the same rate as your heart, making it easy for the love of your life to see when your heart is aflutter. Video demonstration is just past the break, and yes, it’s about as precious as you’d imagine.
