For trans-femoral (TF) amputee, the prosthetic knee component performs important roles to assist the motion of prosthetic leg during gait. Even though the variety prosthetic knee component can perform variety functions, the stair ascending gait still be the challenge mode of gait for TF amputee as the unexpected environmental had to be faced daily. This study is aiming to establish the design of the...
The study aimed to investigate and compare characteristics of Bombyx mori silk film coated with mimicked re-self assembly collagen type I under various conditions concentration [0.25,0.5,1.0,2.0 mg/ml]. The thin films consist of collagen fibrils and result from the self-assembly of collagen. The morphological characteristics observed by scanning electron microscopy (SEM) showed that when increased...
A novel co-culture device of neuronal cells was developed for analysis of cell interaction between a normal cell and an Alzheimer's disease infected cell. The device consisted of co-culture chamber system and a microelectrode arrays(MEA). The chamber system has a central chamber and three peripheral compartment chambers, connected by micro-channels. Rat hippocampal neurons were cultured separately...
Online EEG artifact suppression system is a crucial function of real-time Brain Computer Interface (BCI) applications. EEG artifacts significantly affect the accuracy of feature extraction and data classification for estimating cognitive states in Neurofeedback Training (NFT) systems. The EEG artifacts derived from ocular and muscular activities are inevitable and unpredictable due to subject's physical...
The ECG is a method for the detection of cardiovascular disease is simple and effective. The ECG. Check that the electricity produced on the heart muscle, cardiac compression. At the point where the heart muscle cells that can create a special type of electricity itself. We call this point that Sinus node electrical current to run through the muscles of the head room on the power that we have called...
Recent technological advances in wireless body sensor networks (WBSN) have made it possible for the development of innovative medical applications to improve health care and the quality of life. Electroencephalography (EEG)-based applications lie at the heart of this promising technologies. However, excessive power consumption may render some of these applications inapplicable. Hence, intelligent...
This study was conducted to statistically recognize the walking, jogging, and running activities by using accelerometers build-in a smartphone. Using the smartphone causes the user need not to carry another device more. The advantage of the study is to observe remotely any movement of an interested person at all time so the observer can manage appropriate program for exercise, monitor energy consumption,...
Telecommunication systems for the pharmacists to support the outpatient medical treatment have been gaining attention. However in the conventional systems, low usability and interactivity of the system became key problems to support medication. In this research, we developed a patients-pharmacists interactive communication system and investigated it's benefit through a 2-month field trial. We carried...
With the widespread adoption of increasing and high-throughput sequencing data, the need for easy access to biomedical analysis tools, efficient data sharing and retrieval has presented significant challenges. Galaxy helps to address this problem by providing an open, Web-based platform for performing accessible and reproducible genomic analysis. To meet the needs for variable computing and storage...
Drug concentrations in blood are good indexes for drug thearpy. This study proposed an approach based on Raman spectroscopy of tears for a rapid and minimally invasive monitoring of the concentration. Tear fluid reflects the drug concentration in blood and its collection can be performed easily and noninvasively in comparison to blood drawing. Raman spectroscopy is a rapid and sensitive analytical...
Left ventricular assist devices (LVADs) have confident in treatment for end-stage heart failure. The mainly development of LVADs design based on a rotary blood pump (RBP) technology for both long-term and short-term supports. The first generation of LVADs was the pulsatile system based on volume displacement technology. For the second generation of LVADs, novel LVADs were developed to be a non-pulsatile...
Recent researches have demonstrated implications of Arterial Pulse analysis from Radial and Brachial artery on cardiovascular, renal and autonomic nervous system, as early indicator of major ailments. We have developed a low-cost Arterial Pulse Analyzer which provides run-time display of Arterial Pulse waveforms during the test as well as provides analysis of the waveforms in digitally storable format...
This paper presents a concept of the design and development of an infant incubator by increasing a number of an air flow slot for air-inlet and air-outlet inside a double wall infant incubator. The number of airflow inlet slot is increase to 2 while an airflow outlet slot is to 4 at the lateral side. The study is done by using FEM simulation to compare between single air flow slot and multi air flow...
Conventional drowsiness detection devices are usually equipped with infrared LEDs and CCD cameras; however, they are adversely affected by factors such as ambient light and the use of eyewear. Drowsiness detection by other methods would thus improve such devices. This study examines skin potential activity, which is not affected by the aforementioned factors. Response performance during monotonous...
In this paper, we identify feasibility of energy harvesting using parametric amplification phenomenon of piezoelectric bimorph cantilevers for bladder pressure sensing. We simply fabricated piezoelectric bimorph cantilevers by bonding 110 µm thick polyvinylidene fluoride (PVDF) and 500 µm thick polycarbonate (PC) using an epoxy. The piezoelectric bimorph cantilever was 34.8 mm long, 10 mm wide, and...
An epileptic EEG exhibits various temporal characteristics corresponding to different states of the brain. In this paper, the temporal characteristics of wavelet subbands of scalp epileptic EEG associated with different states of the brain is examined based on an average amplitude of local minima and maxima, referred to as the average local min-max amplitude. The computational results show there are...
This paper presents an analysis of heat transfer from the surrounding area skin of newborn under using infant radiant warmer (IRW) by finite element three-dimensional software. And to compare the results of heat transfer measurements from experiments on the IRW in used everywhere. In this study, results are obtained for a simplified model. It is equipped with. Systems design, the properties of materials...
Parkinson's disease (PD) was described by James Parkinson first time and it is now recognized as the second common neurological disorder after Alzheimer. Since most of the people with PD suffer form speech disorder, it is believed that speech analysis can be considered as the easiest way for PD detection. In this research, we try to use extracted features by genetic algorithm and ANFC for classifying...
This study proposes a piezoelectric polyvinylidene fluoride (PVDF) patch for detecting the movement of the biceps brachii muscle. The polyurethane (PU) elastomer was chosen to perform as an artificial muscle. The PVDF patch rigidly glued onto the stretching PU strip could generate the charge linearly with its applied force. The large strain of 1–4 % of the PU at a low driving voltage has led to the...
A binary search method for fast identification of the time-constant in first order systems is proposed. The unimodality of the Root Mean Square Error (RMSE) is exploited to achieve fast convergence. As an application example, the method is applied to the oxygen transport system of a preterm infant. Performance of the proposed binary algorithm is compared with a direct search method for two different...
