Abstract
The present invention is directed at an electromagnetic field monitoring device configured to continuously monitor properties of an electromagnetic field. The device may be solely powered by the ambient electromagnetic energy of an electromagnetic field, removing any reliance on external power sources or batteries. Monitored properties may include real-time electromagnetic field strength, peak electromagnetic field strength in a time period, electromagnetic field exceedance, and cumulative electromagnetic field dose. The device detects otherwise concealed sources of electromagnetic fields, such as hidden cameras or microphones. The device may be integrated into a variety of products, including, but not limited to, a keychain attachment, lanyard attachment, eyeglasses frame, handheld instrument, identification card, writing instrument, business card, adhesive sticker, ring, or necklace pendant.
