a main on-body component configured to be attached to the patient, the main on-body component having a housing, a first electrode sensor, a second electrode sensor, an acoustic diaphragm sensor, an electronics module within the housing, the electronics module having in operative communication a microprocessor, memory, a first four-channel module, a second four-channel module, a power supply, a wireless communication module including an antenna, and a main-to-peripheral connection I/O module including an amplifier, a filter, and a converter;
a peripheral on-body component configured to be attached to the patient, the peripheral on-body component having a peripheral housing, a peripheral electronics module within the peripheral housing, the peripheral electronics module having in operative communication a third electrode sensor, a fourth electrode sensor, and a peripheral-to-main connection I/O module;
a local wireless access component having an internet connection;
a health data server computer having a database and having program instructions saved to memory and executable by a processor for receiving, manipulating, storing, and transmitting patient health data;
computer program instructions saved to memory and executable by the main on-body component microprocessor for performing the following steps in order:
provisioning connection between the main on-body component and the peripheral on-body component and provisioning connection between the main on-body component and the health data server computer;
obtaining initial sensor data from the main and peripheral on-body components, the initial sensor data comprising heart sound, ECG, lung sound, EMG, EEG, EOG, temperature, and orientation x-y-z axis;
collecting initial sensor data in subgroups of <100 data points at a continuous sampling window frequency (t1+n), said frequency selected from the group consisting of 4 KHz, 1-10 KHz, 2 KHz, and 1-20 KHz;
calculating mean and standard deviation values from subgroups at period t1, and converting each (t1) subgroup value to a (t1) matrix pixel value;
generating an N×N (t1) matrix of matrix pixel values to generate a (t1) signature sensor signal pattern;
continuously calculating subgroup values at periods t1+n, and converting subgroup values to matrix pixel values;
