A Chest‐Conformable, Wireless Electro‐Mechanical E‐Tattoo for Measuring Multiple Cardiac Time Intervals

چکیده
Cardiovascular diseases are the leading cause of death globally. Noninvasive, accurate, and continuous cardiovascular monitoring can enable preemptive detection heart timely intervention to prevent serious cardiac complications. However, unobtrusive, ambulatory, comprehensive is still a challenge as conventional electronics rigid, heavy, or consume too much power for long-term measurement. This work presents thin (200 µm), stretchable (20%), lightweight (2.5 g), wireless, low-power (<3 mW) device that conforms human chest like temporary tattoo sticker, correspondingly known an e-tattoo. e-tattoo features dual-mode electro-mechanical sensing—bio-electric signals via electrocardiography mechanical rhythm seismocardiography. A unique peripheral synchronization strategy between two sensors enables measurement systolic time intervals pre-ejection period left ventricular ejection with high accuracy (error = −0.44 ± 8.74 ms) while consuming very low power. The validated against clinically approved gold-standard instruments on five subjects. good wearability consumption this permit 24-h ambulatory monitoring.

Respiratory modulation of cardiac time intervals.
To determine the effect of respiration on systolic and diastolic time intervals, simultaneous phonocardiograms, carotid pulse tracings, M mode echocardiograms, and respiratory curve tracings were measured in 25 healthy subjects. The positioning of each cardiac cycle in relation to the phase of respiration was assessed and the dependency of heart rate and cardiac time intervals on respiration wa...
متن کاملAtrial electromechanical coupling intervals in pregnant subjects
OBJECTIVE The aim of this study was to evaluate atrial conduction abnormalities obtained by tissue Doppler imaging (TDI) and electrocardiogram analysis in pregnant subjects. METHODS A total of 30 pregnant subjects (28 ± 4 years) and 30 controls (28 ± 3 years) were included. Systolic and diastolic left ventricular (LV) function was measured using conventional echocardiography and TDI. Inter-at...
متن کاملA Multiband Multiple-input Multiple-output Antenna System for Long Term Evolution and Wireless Local Area Networks Handsets
A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...
متن کاملA Deterministic Multiple Key Space Scheme for Wireless Sensor Networks via Combinatorial Designs
The establishing of a pairwise key between two nodes for encryption in a wireless sensor network is a challenging issue. To do this, we propose a new deterministic key pre-distribution scheme which has modified the multiple key space scheme (MKSS). In the MKSS, the authors define two random parameters to make better resilience than existing schemes. Instead of a random selection of these parame...
