Patent attributes
A method includes providing an ensemble of distributed sensors, delivering radio frequency (RF) power to each sensor by inductive near-field coupling by a magnetic field projected by an epidermal transmit (Tx) coil, in each individual sensor, detecting a sparse binary event in its immediate environment, reporting the detected sparse binary event to an external RF receiver hub asynchronously and with low latency, and minimizing error rates due to statistical data packet collisions in asynchronous telemetry by digitally encoding each sensor according to a particular address scheme where each address is one function from an infinite set of mathematically orthogonal functions, enabling a simultaneous detection from up to ten thousand points without interference at a common receiver.
