Brain Sensor

With both electrocardiograms and electroencephalograms, patients have to have electrodes “stuck” on their skin to get good signals.  Bioengineers at UC-San Diego, however, have developed biosensors that detect signals at a short distance from the skin, as in clothing or a head band.  The next step is to build in a Bluetooth transmitter so the sensor can capture data from the heart or brain continuously and send it wirelessly to a receiver for distance monitoring.  MORE
