  • Electromechanical Piezoresistive Sensing of Graphene-based Intracranial Pressure Sensor

    Graphene shows a promising future in the application of biomedical sensors as the piezoresistive sensing elements due to its electromechanical properties. This paper presents the fundamental development stage of graphene-based piezoresistive intracranial pressure sensor, i.e., to determine its diaphragm design, which is made of polydimethylsiloxane polymer. Different thicknesses of a square diaphragm were simulated using COMSOL Multiphysics. The Parametric Sweep function was used to simultaneously simulate the changes of two parameters, namely diaphragm thickness and operating pressure. It was found that the thin diaphragm is more susceptible to deform due to the rapid geometry changes and the differences in modulus of elasticity of the materials used in the design. Meanwhile, the stress experienced by the diaphragm degraded with the increase in thickness. However, a slight modification in designing and positioning the piezoresistors would make the sensor's performance on par with those of thin diaphragm. Hence, by selecting the right thickness and shape of polydimethylsiloxane diaphragm, it will serve as a good platform in developing the graphene-based piezoresistive intracranial pressure sensor.

  • Fabrication of thin layer membrane using CMOS process for very low pressure sensor applications

    A very low pressure sensor has been proposed to be used in the eye for glaucoma treatment with pressure ranging from 10 mmHg to 75 mmHg. This paper presents process development of thin layer membrane for very low pressure sensor application. The structure of the membrane consists of parallel plate which both top and bottom electrodes were fixed at both sides. Utilizing CMOS compatible process, fabrication of the thin layer membrane involved in three stages; i) hole opening etch, ii) sacrificial intermediate oxide release etch and iii) closing of etch holes. Our work focuses on the characterization of holes opening etch size for the intermediate oxide release. Another study was carried out to understand the behavior of sealing off the hole openings etch. This study involved different deposition technique such as LPCVD, PECVD and combination both of them. The findings from these experiments are presented in this paper.

  • Development of ultra miniature 1-french sensors for wireless radial arterial pressure monitoring

    Miniaturized pressure sensors attached to catheters have numerous applications in the biomedical and life science fields including the monitoring of arterial, ventricular, intracranial and intraocular pressures. Recent advances in MEMS (microelectromechanical systems) technology and its associated fabrication processes, such as DRIE (deep reactive ion etching), have allowed for further miniaturization of these devices, expanding the application landscape to include small animal models and new human applications. One such human application is the wireless measurement of radial arterial blood pressure (BP). The goal of this research program is to produce a truly portable wireless radial arterial monitoring system using a custom-designed ultra-miniature pressure sensor appropriately sized to fit within the tip of a 1-French catheter (333 micron), so that convenient in-vivo measurements of BP are possible. The proposed system consists of two assemblies. The sensor, catheter, and wristband containing the battery and telemetry circuit form one assembly and the portable wireless PDA-sized transceiver module forms the other. This paper reports on the custom miniature MEMS pressure sensor developed for this application.

  • Tiny MEMS-based pressure sensors in the measurement of Intracranial Pressure

    This study presents a tiny pressure sensor which is used to measure the Intracranial Pressure (ICP). The sensor is based on the piezoresistive effect. The piezoresistive pressure sensor is simulated and designed by using nonlinear programming optimizing and Finite Element Analysis (FEA) tools. Two kinds of sensor sizes are designed in the case of childhood and adult. The sensors are fabricated by Microelectro Mechanical Systems (MEMS) process. The test results yield sensitivities of 1.033×10-2mV/kPa for the childhood type detection and 1.257×10-2mV/kPa for the adult detection with sensor chip sizes of 0.40-0.40 mm2and 0.50×0.50 mm2, respectively. A novel method for measuring ICP is proposed because of the tiny sizes. Furthermore, relative errors for sensitivity of pressure sensors are limited within 4.76%. Minimum Detectable Pressure (MDP) reaches 128.4 Pa in average.

  • Possibility of registration of changes in the human body at influence of harmful production factors by means of the polygraph

    Production factors can influence the person in the course of his work dangerous (defiant injuries) and harmful (defiant diseases). One of unhealthy physical factors are electromagnetic fields (EMP). World Health Organization (WHO) states that electromagnetic fields are the most dangerous environmental factors. Studies showed that people exposed to industrial electromagnetic fields had neurological problems as well as cardiovascular diseases. Numerous researchers point out that low frequency electromagnetic field is biologically damaging. Magnetic fields of industrial frequency are widely occurring in electric power industry and their impact on people health is negative. Commercial frequency magnetic fields occur near all electrical plants, overhead power transmission lines and other current distributors. This research aim is instrumental registration of magnetic field presence and its effect on the human brain. The following equipment was used in the research: polygraph “Barier-14” (person's psychophysical condition analyzer), field density detector PZ-50V and special helmet with inbuilt coils serving as the magnetic field source. Men and women from 18 to 65 took part in the research with the sample size of 60 people. The research found and registered negative effect of magnetic field on human body. Furthermore, the research detected the most affected organism parameters when exposed to magnetic field.

  • A signal analysis algorithm for determining brain compliance non-invasively

    Patients with increased intracranial pressure (ICP) caused by hydrocephalus or brain injury have poor brain compliance or increased brain stiffness. The condition is commonly treated by a surgical diversion of cerebrospinal fluid (CSF) through placement of a ventriculoperitoneal (VP) shunt. These inserted devices frequently fail and require replacement. Assessment of failed devices typically requires an invasive surgical procedure to implant an ICP sensor. Brain compliance can be determined non-invasively by comparing the intracranial pressure (ICP) waveform to the digital artery waveform. The ICP waveform is derived from a piezo sensor snugged into the external ear canal and worn as a headset. The digital artery waveform is derived from a stand pulse oximeter. Digital signal processing performed on sampled data from these two sensors shows a time-lag or phase relationship between the two waves which widens with worsening brain stiffness or compliance. An algorithm is presented that shows how these signals can be used to compute brain compliance. An instrument designed to calculate real-time brain compliance to aid healthcare professionals is described.

  • Integration of Wearable Wireless Sensors and Non-Intrusive Wireless in-Home Monitoring System to Collect and Label the Data from Activities of Daily Living

    We describe an inexpensive in-home monitoring system designed to assist patients with traumatic brain injuries plan and execute daily activities. The system consists of fixed and wearable wireless sensors, including motion, pressure, door, flow, accelerometer, magnetometer, temperature, light and sound sensors. The sensors provide information that can be used to localize the patient, detect the activity they are engaged in and interruptions that may prevent them from completing the activity in a timely manner. During the system design and training phase, we augment the system with time stamped video and audio collection to provide a ground truth and label training data.
