Bluetooth technology could be used to monitor unborn babies' heart rates  (Source:
The Bluetooth method is 98 percent more accurate than the ultrasound-based Doppler shift technique

Researchers from India have developed a fetal heart rate monitoring system using Bluetooth technology.

Vijay Chourasia, study leader from the LNM Institute of Information Technology in Jaipur, and Anil Kumar Tiwari of the Indian Institute of Technology Rajasthan, have found that a Bluetooth fetal heart rate monitoring system is much more accurate for long-term care than a traditional stethoscope.

According to Eurekalert, the Bluetooth system checks the heart of an unborn baby much like a conventional stethoscope, but is much more convenient and accurate. The system is convenient because there are no cables and it also has low power consumption, allowing mothers to use it without assistance from medical professionals. 

The Bluetooth system is also safe because it doesn't emit an ultrasound and is non-invasive. It doesn't emit any other sort of energy either.

The research team tested the system on 33 expectant mothers at different points throughout the pregnancy. According to the researchers' results, the Bluetooth method is 98 percent more accurate than the ultrasound-based Doppler shift technique.

The paper will be published in the International Journal of Computers in Healthcare.

Curious, I went to read the source and wow, this totally butchered the original. For those interested:

Let me re summarize it for you:

Team used bluetooth to replace cabling of traditional vital sign monitoring systems in prenatal units. They did so because it's more convenient (mother can use it themselves, data sent wirelessly to be analyzed elsewhere, no need for intervention by staff/doctors in taking these vital signs). To test it, they compared this new method to the gold standard, which is ultra-sound based doppler technique. They found that this new method is comparable, 98% accurate as compared to the gold standard. Therefore, this is safe, accurate, convenient to use.

Thanks for the clarification.

It seemed that they were using BT to really do the monitoring, and it was +98% (almost twice) effective...

Tiffany, WTH?!?!?!?!?! How about writing clearly and stating the facts?!

DailyTech, you should pull this news article down and put Tiffany through writing school. This article is horribly written and reflects poorly on the quality of articles here on DailyTech.

Tiffany, shame on you. Drink some coffee and try this again.

As an MD, I can say this article is complete garbage and makes no sense. I'm curious as to what the original article says - not the summary, but the actual article from the journal. We don't use stethescopes for fetal heart rate monitoring, and the ultrasound they use for current monitoring is harmless. The system likely still uses either phonocardiography or ultrasound and uses BT as signal transmission for data. Pacemakers have used similar technology for a while to transmit data remotely.

I don't understand this article at all. I thought bluetooth is a data transmission method to replace a cable link. What is all this jargon about ultrasound and stethoscope? Besides signal transmission, are they using the 2.4 GHz bluetooth radiowave for diagnostic purposes as well? This is quite sloppy and needs a lot of clarification.
