A system and method that uses non-invasive method, such as a wearable module equipped with sensors placed on a subject connected to a computer-linked module, to monitor life signs like heartbeat waveforms, body temperatures, indicating the health of a living being or a dynamic system. The health of the system is defined by a set of known good spectra with deviations triggering alerts. A garment embedded with a piezoelectric material and a temperature sensor, when placed in contact with the body, captures acoustic waves from the heart and body temperature. Both sensors are connected to a garment-mounted module with a flexible printed antenna. Another module with reconfigured daughterboard software forms a bidirectional wireless data connection to a computer. A software program compares the received spectrum to its database spectrum based on a set of rules and alerts the user when it deviates.
