A Modular Android-Based Multi-sensor mHealth System

This paper describes the design and methodology for building a versatile, portable and user-friendly mHealth solution for capturing data using multiple electronic sensors. The paper identifies the various dimensions of information that need to be captured to provide a degree of trustworthiness in the system, and describes the protocols and mechanism for its realization. The application uses a set of basic electronic biomedical sensors to capture vital medical information of the patient, combines these with personal, biometric and contextual information and generates an XML based encounter report. The biomedical sensors are connected to a micro-controller that interfaces to a smartphone via one of many possible connectivity modes. The applications running on the smartphone can then analyse the data and metadata and provide feedback to the health care provider and patient, or upload the XML report to a server on demand.
