Abstract

This paper presents a miniaturized electromagnetic wave detector. The dimension is reduced down to $31{\times}18{\times}13.5mm^3$ by using common OP-AMPs for amplification and oscillation. The strength from wave radiators is indicated by a color LED; green, orange and red colors mean the low, the middle and the high level, respectively. An alarm bell rings as the wave strength becomes above high level. The detector uses 3V battery. The detector could be used for a cellular phone decoration, a necklace pendant and a key holder.
