Diastolic blood pressure estimation using only pulse arrival time was not sufficient. To overcome it, arterial stiffness was considered. Several parameters related to information, time, slop information in photoplethysmography signal were chosen and investigated. Five subjects executed Valsalva Maneuver which caused the blood pressure variation. Time from maximum point of first derivative wave to...
The aim of this paper is to find a relation between HRV parameters of ECG and stressful driving situation in the real road through various tests. First, we gave a stress to the subject by increasing the driving speed using driving simulator in the laboratory. Second, the subject drove the vehicle on the real road. Through let him drove in the busy narrow street, we evoked stress. ECG and PPG signal...
Home Integrated Health Monitor (HIHM) was developed for ubiquitous home healthcare. From quantitative analysis, we have elicited modal of chair. The HIHM could detect Electrocardiogram (ECG) and Photoplethysmography (PPG) non-intrusively. Also, it could estimate blood pressure (BP) non-intrusively, measure blood glucose and ear temperature. Detected signals and information were transmitted to home...
