A wearable garment with sensors attached to obtain physiological data. The sensors are incorporated to form a body area sensor network to obtain the data. This provides patients with improved health monitoring by aggregating multiple interconnected nodes on a human body for sensorimotor measurements and provides patients with quantitative measurements of their progress. The data is obtained in a way that allows for the number of transmissions to be reduced thereby conserving the energy of the wearable devices. This is made possible by each sensor reducing the number of samples by eliminating predictable samples and configuring the sensors to pack the data efficiently. A neural network can determine whether a sample can be skipped or needs to be reported. A long short term memory architecture creates a waveform for a given snapshot of samples based on the previous samples regardless of whether these samples were reported or predicted.

A sensor apparatus configured to detect at least one physiological parameter of a subject includes a sensor that detects at least one physiological parameter of the subject as sensor data. An energy harvesting circuit includes a plurality of energy harvesting devices configured to harvest ambient energy from an environment of the subject. The energy harvesting devices generate power at a plurality of voltage potential levels from ambient energy. A conditioning circuit is configured to adjust the plurality of voltage potential levels to a bus voltage supplied to a supply bus. A controller receives operating power via the supply bus and controls the activation of the sensor and the wireless communication circuit.

Systems, devices, and methods are provided for changing the power state of a sensor control device in an in vivo analyte monitoring system in various manners, such as through the use of external stimuli (light, magnetics) and RF transmissions.

In some aspects, a device is disclosed for monitoring load bearing of a foot. The device can include a housing, a transmitter, and a pressure sensor. The housing can be positioned under a foot of a patient and attach to the foot. The transmitter can wirelessly transmit an indication that a portion of the foot is supporting at least a threshold weight. The pressure sensor can wake up from a sleep mode responsive to the portion supporting at least the threshold weight, cause the transmitter to transmit the indication, and return to the sleep mode.
