Smartphone Homecare Monitoring of Hearts

Homecare monitoring blood pressures and heartbeats are commercially available using dedicated devices, for example, wrist watch, pulse oximetry. With the advent of Smartphone and compressive sensing technology, we wish to monitor precisely the electrical waveforms of heartbeats called the electrocardiography (ECG) for an aging global villager biomedical wellness homecare system. Our design separates into 3 innovative modules within the size-weight and power-cost bandwidth (Swap-CB) limitation. We develop each separately but in concert with one another: (i) Smart Electrode (adopting a low-power-mixed signal embedded with modern compressive sensing firmware and applying the nanotechnology to improve the electrodes’ contact impedance as well as novel transduction mechanism, between ECG and electronics, e.g., a pressure mattress coupling, or fiber-optics coupling); (ii) Learnable Database (utilizing adaptive wavelets transforms for systolic and diastolic P-QRS-T-U features extraction Aided Target Recognition and adopting Sequential Query Language for a relational database allowing distant monitoring and retrievable); (iii) Smartphone (inheriting a large touch screen interface display with powerful computation capability and assisting caretaker reporting system with GPS and ID and two-way interaction with patient panic button for programmable emergence reporting procedure). While (i) is novel, (ii) and (iii) are mature. Together, they can eventually provide a supplementary home screening system for the post- or the prediagnosis care at home with a built-in database searchable with the time, the place, and the degree of urgency happened, using in situ screening. 1. Introduction Home-alone senior tends to suffer and worry about midnight and early morning crisis, heart attack, or stroke. While their bodies secrete hormones regulating hearts and blood pressures ready for the wake-up actions, their limbs are still stiff suffering bad circulations over the sleep. For caretakers, we design an affordable, and comfortable biomedical wellness (BMW) monitoring device of detail electrocardiogram (ECG) waves for early warning monitoring at homes. Thus, we review heart monitoring ECG as a common sense baseline, before we present compressing sensing technology (reader may skip over the following and go directly to Compressive Sensing). A healthy heart is controlled by a sequence of electrical signals fired in order, following the proper timing with an oxygen-rich red blood taking from our lungs to the Aorta upper chambers called Atrium, and down to the lower chambers
