Title: investigation on wireless medical requirement of blood pressure measurement
supervisor: Dr Harsa Amylia Mat Sakim
Requirement:
Student must be interested in designing of medical instruments; specifically using wireless technology. MEMs technology may be applied. Electronics student preferred. (Co-supervision with Dr Widad Ismail)
Synopsys:
Pressure is defined as force per unit area that a medium exerts on its surroundings. For example, pressure, P, is a function of force, F, and area, A.
P = F/A
A pressure measurement can be described as either static or dynamic. The pressure in cases where no motion is occurring is referred to as static pressure. Examples of static pressure include the pressure of the air inside a balloon or water inside a basin. Often times, the motion of a fluid changes the force applied to its surroundings. Such a pressure measurement is known as dynamic pressure measurement. For example, the pressure inside a balloon or at the bottom of a water basin would change as air is let out of the balloon or as water is poured out of the basin. There are several types of pressure sensors which mechanisms depend on the medium it is to be used. In a fluid environment, a pressure sensor measures the pressure, at a point in a fluid network. By monitoring the pressure at all nodes in a fluid network, one can often solve the network. As compared with flow sensors, pressure sensors often have less cost to achieve a similar result. When pressure is applied to a pressure sensor, it triggers a switch. This turns an electrical circuit (usually) on or off. In measuring blood pressure, the sensor has to be highly sensitive as the pressure exerted is small as compared to measurements made in industry. One way of constructing a pressure sensor is to use MEMS technology. This project is to investigate the requirements to ‘capture/display’ the blood pressure measurement using wireless technology.
