Abstract: A biometric monitoring system comprises a substrate with a first surface having a length and a width. A first transmitting antenna is coupled to the first surface at a first end of the length of the first surface. A second transmitting antenna is coupled to the first surface at a second end of the length of the first surface. The first and second transmitting antennas extend across the width of the first surface. A plurality of receiving antennas are coupled to the first surface, each of which extends across the width of the substrate and is spaced apart from an adjacent receiving antenna along the length by a predetermined distance. A controller is configured to supply a first signal to the first transmitting antenna and sequentially measure a transmission coefficient or voltage of the first signal at the plurality of receiving antennas until an attenuation in the transmission coefficient or voltage exceeds a threshold.

Abstract: An on-body antenna is provided that overcomes mismatch loss problems associated with current on-body antennas and is capable of operating over a wide range of frequencies with low transmission loss. At least a first antenna element of the on-body antenna is configured to receive an oscillating electric current and to radiate an oscillating electromagnetic field over a predetermined range of frequencies. The first antenna element is made of non-electrically-conductive material having a first relative permittivity. At least a second material having a second relative permittivity can be disposed on or in the first antenna element. Disposing the second material provides the first antenna element with an effective permittivity that can be closely matched to a frequency-dependent permittivity of biological tissue of a subject. The first non-electrically-conductive material and the second material can be preselected to have relative permittivities that allow anisotropy to be achieved.

A wearable coil configuration of the system comprises at least first and second electrically-conductive coils adapted to be secured to a subject in a predetermined spatial relationship and orientation relative to one another. The first coil acts as a first transmitter and generates a first magnetic flux when a first electrical current is passed through it. The second coil acts as a receiver. The first magnetic flux induces a first electrical current or voltage in the second coil. A measurement instrument of the system is configured to measure the first electrical current or voltage and to output a first measurement signal. A processor, which may be part of, or external to, the system is configured to execute a motion monitoring algorithm that processes at least the measurement signal to determine at least a first motion made by the subject.

Abstract: Disclosed and described herein are systems and methods of energy generation from fabric electrochemistry. An electrical cell is created when electrodes (cathodes and anodes) are ‘printed’ on or otherwise embedded into fabrics to generate DC power when moistened by a conductive bodily liquid such as sweat, wound, fluid, etc. The latter acts, in turn, as the cell's electrolyte. A singular piece of fabric can be configured into multiple cells by dividing regions of the fabric with hydrophobic barriers and having at least one anode-cathode set in each region. Flexible inter-connections between the cells can be used to scale the generated power, per the application requirements.

Abstract: An electromagnetic bio-signal detector to monitor very weak evoked action potentials associated with neurotransmissions is described. The small induction-coil array detector and integrated circuit design enables the device to have a small and possibly portable form factor while minimizing cost. Advanced signal processing methods enables the device to detect very weak electromagnetic signals without the need for shielding to reduce electromagnetic background emissions. The combination of cost, size, and sensitivity affords the electromagnetic bio-signal detector broad utility both inside and outside hospital settings and for numerous diagnostic and treatment feedback applications.
