1. A system comprising:
a wearable device having a processor and an addressable memory and a plurality of sensors, wherein the plurality of sensors comprises an electrical and biopotential sensor, an optical module, an impedance matched acoustic module, a temperature sensor, and an inertial measurement unit (IMU); and
a secondary receiving unit having a processor and an addressable memory;
wherein the wearable device is configured to:
receive a request from the secondary receiving unit to generate a series of recordings using the plurality of sensors based on a customized recording schedule, wherein the series of recordings is generated via taking a set of measurements;
detect a current motion associated with a user of the wearable device for generation of the series of recordings based on detecting motion by the IMU configured to measure current motion levels and always be on even while other sensors of the plurality of sensors are asleep;
delay generation of the series of recordings via taking the set of measurements for a period of time, if the detected current motion is determined to be above a threshold whole measure;
execute generation of the series of recordings via taking the set of measurements, if the detected current motion is determined to be below the threshold whole measure;
determine, during the execution of generation of the series of recordings via taking the set of measurements, whether any detected motion is above the threshold whole measure, wherein motion levels are detected and monitored continuously during the taking of the set of measurements;
extend the recording length by a predetermined period of time above the threshold while motion is being detected to be above the threshold, thereby dynamically adapt recording lengths based on sensor readings and maintain data quality of the recordings;
transmit, via an established connection to the secondary receiving unit, the generated series of recordings and a flag based on the extension of recording length to indicate one or more sections of a current measurement are tagged as sections of high motion; and
receive from the secondary receiving unit a new recording schedule based on the flagged transmitted generated series of recordings.
