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.

Apparatus and method to capture body signals with conjugate coils and paired coils

A system is disclosed including: one or more electroencephalography (EEG) sensor nodes in a fully reconfigurable sensor network configured to detect electrical signals indicating activity of a brain of a subject and to transmit signal information relating to the detected electrical signals, each EEG sensor node embodying an analog front end (AFE) circuit, and a centralized command control node (CCN) in the sensor network in communication with the one or more EEG sensor nodes and configured to receive the transmitted signal information from the one or more EEG sensor nodes and to perform a processing technique on the received information resulting in processed signal data, wherein the one or more EEG sensor nodes are configured to detect the electrical signals without a driven right leg (DRL) circuit in the sensor network.

Fully reconfigurable modular body-worn sensors

In one embodiment, a method is disclosed in which an analog sensor receives an electromagnetic (EM) wave (e.g., a radio frequency signal) from an interrogation device. The sensor converts a biological measurement of a subject into an electrical resistance and modulates a response to reflect the incident signal based on the electrical resistance. The sensor then provides the response to the interrogation device that corresponds to the biological measurement.

Wireless analog passive sensors

A multilayer printed circuit as well as printed passive and active electronic components using additive printing technology is provided. The fabrication process includes a substrate and a first conductive layer that is printed with conductive ink on the substrate. An insulation layer that has uniform thickness is printed on the first conductive layer and the substrate, less via cavities, test point cavities, and a surface mount component contact point and mounting cavities. The insulation layer is replaceable with resistive layer or semi-conductive layer to fabricate electronic components. The vias are printed with conductive ink inside of the via cavities. Additionally, a second conductive layer is printed on the vias and over the insulation layer. The insulation, resistive, or semi-conducting layer, the vias, and the conductive layers are repeatedly printed in sequence to thus form the multilayer printed circuit.
