Developing MEMS sensors with a high strain sensing range (up to 0.6) and a stepwise sensing mechanism could enable widespread downstream applications, by allowing intimate, mechanically conformable integration with soft biological tissues. Most approaches to date focus on challenges to associate the sensing mechanism with high peak strains under large deformation. By designing and characterizing test...
This paper reports on the sensing of large strain using a mechanically actuated switch gate and a variable resistor surface creasing test structure. Test structures with different gate and interconnect/wiring geometries have been designed, fabricated and characterised. They respond to designed strain values with a reduction in device resistivity of 11 to 12 orders of magnitude. Results from strain...
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...
The aim of this work is to study the feasibility of reconstruction mathematical model of cardiac tissue from intracellular recordings. It is studied using simulated data and the presented method is applied to the Aliev-Panfilov model. A dissociated scheme is proposed and the estimation of some parameters is investigated in case of ideal or noisy data. The influence of the number and distribution of...
Recent studies showed that spiral waves could be involved in cardiac fibrillation. Changing the dynamics of spiral waves and stoping them by electric stimulations provide a potential way of defibrillation. However, electric stimulation could bring some serious problems to patient as well. So, our aim in this paper is to determine an optimal stimulation mode, such as the number of required stimulated...
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...
