Abstract: A health-monitoring system and method use artificial intelligence for monitoring patient health based data acquired from one or more health-monitoring data-sources. The health-monitoring data-sources may include one or more wearable devices, one or more portable health-monitoring devices and other data sources. The health-monitoring system may use artificial intelligence to analyze acquired health data and physiological measurements for monitoring patient health.

Abstract: An electrochemical-sensor structure having a substrate and a nanostmctured-sensing surface that receives a volume of a sample fluid. A sample region of the electrochemical-sensor structure for receiving the sample fluid volume is sized such that the volume of the fluid is sufficient to operatively cover a portion of the sample region of the electrochemical-sensor structure including the nanostructured-sensing surface. The electrochemical-sensor structure is connectable to a portable point-of-care (PoC) device. The PoC device may detect the energy properties of the sample fluid from the sample region of the electrochemical-sensor structure, to produce a signal comprising a fluid reading wherein the fluid reading is related to the energy properties of a biomarker in the sample fluid thereby indicating the presence, the absence, or the quantity of the biomarker in the sample fluid.
