Low cost wearable sensor for detecting electromagnetic field

Title: Electromagnetic Field Detector Bracelet

Authors: Cati Vaucelle, Hiroshi Ishii and Joe Paradiso (Massachusetts Institute of Technology, MIT Media Lab)


In this paper 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 an object used frequently. Our technology thus supports 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.
