Hybrid electromagnetic field signal detection system for human bioelectrical signal monitoring

A system for detecting bioelectrical signal, the system comprising:

• a reference module having a first electrode to detect a reference electrical signal;
• a contact module having a second electrode to detect a contact electrical signal;
• an antenna module, the antenna module including (1) an antenna to detect a non-contact EMF signal, and (2) an antenna circuit module to perform wideband tuning and amplify the non-contact EMF signal;
• a receiver module, the receiver module including (1) an impedance matching module to match a source impedance of the antenna module, the reference module, and the contact module;
• and (2) a differential amplifier to amplify the difference between the reference signal and the non-contact EMF signal to produce a non-contact bioelectrical signal, and to amplify the difference between the reference signal and contact signal to produce a contact bioelectrical signal;
• and
• a signal processing module including a processor to apply a filtering algorithm to increase the signal-to-noise ratio of the bioelectrical signals and to perform digital signal processing on the bioelectrical signals.
