Cost-Effective Wearable Sensor to Detect EMF

Groups

We present the design of a cost-effective, wearable sensor to detect and indicate the strength and other characteristics of the electric field emanating from a laptop display. Our bracelet can provide an immediate awareness of electric fields radiated from a frequently used object, thus supporting awareness of ambient background emanation beyond human perception. We discuss how detection of such radiation might help to "fingerprint" devices and aid in applications that require determination of indoor location.
