Prabhakar Zutshi Baleigh Clark Bryn Carroll The job titles ‘Electrical Worker’ and ‘First Responder’ consistently rank in the top ten most dangerous jobs in the United States. There are around two deaths by electrocution per day for electrical workers in the US and even more in less developed countries with less rigorous safety standards. These deaths frequently come as a result of accidentally touching a live wire the individual was not aware of, voltage leaks, arc flashes, etc. We need a measure to reduce the number of these preventable deaths. The proposed device is a pair of wearable, insulated gloves that can detect the induced electromagnetic fields (EMF’s) generated by AC power lines and wires from a distance. The gloves would then vibrate with increased intensity the closer/stronger the field became. This tactile response would inform the electrician or first responder of a nearby live wire/electrical source that could harm them, that they may or may not have been aware of previously. There are two potential designs we would like to pursue. A magnetometer based glove, and an electric field meter based glove. The magnetometer based glove would most likely utilize the MAG3110 IC. This magnetometer would be able to detect the alternating magnetic field generated by the wires. It's fast data sampling rate would allow us to determine if the magnetic field we are detecting is indeed generated by an AC wire. There is also little ambient magnetic noise in the environment reducing the need for much signal processing. The microcontroller would then take those field strengths and translate it into vibration via the vibration disks implanted in the glove. The second design that we could use is a electric field meter design. This design uses the electric fields generated by all charges to serve as our signal. I don't have a concrete recommendation for the exact detector we will use, but it will either be a electrometer (Capacitively coupled D.C amplifier with a shunt capacitor for calibration) type or an A.C carrier type, as they are low cost, simple and small; all properties we desire. The ambient electric fields in our environment are often large due to electronics so we will need to be able to zero it in respect to it's environment. Thankfully, electric field strength increases greatly, so any large spikes in electric field strength could be the filter we need to determine if we are detecting the correct signal.
