“…Each solution combines one or more of the aforementioned measurements, in an ad-hoc manner, principally driven by a specific project or user requirements. For instance, heart activity, blood pressure, and glucose are monitored and managed in [ 11 ], glucose levels and heart activity are addressed by [ 12 ], pulse and temperature signals are recorded by [ 13 ], a pulse oximeter and GPS data are employed by [ 14 ], while cardiac, respiratory and motor activity are monitored by [ 15 ]. Systematic reviews of mobile health applications provide lists and insights on the various solutions that have been developed [ 7 , 9 , 10 , 16 ].…”
