A novel micromachined electrode is designed and fabricated for a BSN-based vital signs monitoring system. Both theoretical calculation and ANSYS simulation show that buckling problem will not occur for the proposed microneedles during insertion process. The BSN-based vital signs routine monitoring system, which comprises of wireless mote, analog amplifier circuit board and SpO2 (Saturation of Arterial...
Based on the experimental model, in this study, the heart rate variability (HRV) is investigated at a microscopically level in a cardiac cells culture by analyzing the field potential (FP) signals using a wavelet transform. Our results suggest that wavelet analysis provides useful information for the assessment of dynamic changes and patterns of FP train.
This paper proposes a novel micromachined physiological recording electrode with hollow microneedles for Electrocardiography (ECG) measurement. Compared to the standard commercial wet electrode and other proposed dry electrodes, a unique characteristic of this device is that a hollow microneedle array is made of silicon, which can pierce through the outer skin surface, lowering the electrode-skin-electrode...
Wearable medical devices provide great convenience to the elderly for the monitoring of vital signs at home. This paper describes a novel long-term wearable vital signs monitoring system which can real-time measure physiological signs such as ECG, SpO2 (saturation of arterial oxygen) and systolic blood pressure. The proposed device is easy to wear, convenient to use and has almost no impact on the...
Wearable medical devices provide great convenience to the elderly for the monitoring of vital signs at home. This paper describes a novel wrist-worn vital signs routine monitoring system which can measure physiological signs including ECG, SpO2 (Saturation of Arterial Oxygen) and systolic blood pressure in real-time and with almost no impact on quality of life. The proposed device is easy to wear...
A wearable BSN-based ECG-recording system is proposed for long-term and continuous arrhythmia monitoring. A novel micromachined Pt electrode is specifically designed, fabricated and integrated into a wearable chest band. A miniaturized PCB for ECG analog front-end is fabricated, and can be plugged on the BSN node to wirelessly transmit the signal to a hand-held device. Wavelet denoising is implemented...
