Week 3

Date: 30th January - 3rd February 2012

Conducted lab experiment of Electrooculogram (EOG) Measurement on Thursday (02/02/12) at HPL 209. The goal of the experiment is to acquire and understand the electrical alteration in the muscles that control the eyeball motion. In this experiment, I was assisted by my classmate, Ms. Dalilah.

Equipment used: KL-72001 Main Unit, KL-75003 Electrooculogram (EOG) Module, Digital Oscilloscope, KL-79101 5-Conductor Electrode Cable, disposable body surface electrodes, RS-232 cable, connecting wires, and 10-mm Bridging Plugs.

KL-72001 Main Unit and KL-75003 Electrooculogram (EOG) Module

Dalilah and I were trying to obtain result on Digital Oscilloscope

The electrodes placement were on upper, lower, left, and right of the eye, and the reference electrode on the frontal lobe. The experiment results as shown below:

Distorted signal where subject wriggle the electrode cables and  perform rapid blinking

Yellow signal indicates Right & Left movement while Blue signal indicates Up & Down movement of the eye

The lab experiment that was conducted did not satisfy my lab objective. The output signals were distorted whereby it display lots of noise signal. Hence, I decided for my next lab experiment would be involving multimeter measurement.

My lab experiment was assisted by Ms. Dalilah with the presence of my FYP Advisor, Mr. Syazwan
