1. A method comprising:
providing an ensemble of up to ten thousand 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 assigning to each sensor a unique address according to a particular address scheme where each address is one function from an infinite set of mathematically orthogonal functions convolved with a physically unclonable function, enabling a simultaneous detection from up to ten thousand points without interference at a common receiver.
