The Design of Multi-Parameter Bio-Signal Sensor for Applying a Smartphone m-Health Service

Abstract

In this study, the multi-parameter bio-signals sensor was proposed to apply smartphones into m-health service application. The proposed sensor for the experiments was consisted of one set of two small devices; the size of each sensor was 25 mm x 20 mm x 4 mm. This sensor was made of either copper or titanium in order to pursue the better body affinity as well as electric conductivity. A manufactured sensor was able to measure for major bio parameters including electrocardiogram (ECG) signal of a channel, temperature,photoplethysmography, and body fat. Further, independent analogue hardware was manufactured to measure the each bio parameter. In results, bio parameters were easily obtained and they will be effectively applied into smartphones.
