Abstract
A wireless resistive analog passive (WRAP) sensor system using inductive coupling between two or more planar printed spiral coils (PSCs) configured to capture various physiological signals, such as, but not limited to, heart rate, respiration rate, pulse oxymeter, and core body temperature. The sensor system particularly useful for capturing physiological signals that require differential inputs, such as an ECG, EKG, EMG or EEG signals. Wireless induction coupling signals are transmitted over longer range using a fully-passive (i.e., battery-less) range extender circuit comprising a paired coil. The sensor system may include body-worn, fully-passive (battery-less) sensors.
