  1. Wearable Device Monitors Sleepiness

    Walter Karlen and his colleagues in Lausanne, Switzerland have published an interesting article in this month's IEEE Transactions on Biomedical Circuits and Systems about a wearable device that could be used to monitor drowsiness. Basically, they took a shirt and mounted various detectors on it. A belt running around the ribcage measures respiration; gel electrodes fixed to the pectoral area read out an electrocardiogram; and other electrodes detect muscle activation. The whole thing runs off a battery that's also mounted right on the shirt. The approach combines a lot of the techniques traditionally used to determine whether a person is …
