University project
Energy harvesting for wearable sensors- 2022
· Worked in two people group with a supervisor to design a pair of smart shoes that can achieve energy self-sufficiency by using solar film and piezoelectrical.
· Lead a team of two people and make a plan of a reasonable timeline and assign duties to the group member.
· Mainly responsible for circuit design, soldering each element, and test circuit.
· Successfully finished project with function of measuring humidity and heart rate and energy harvested from solar and piezoelectrical can be used to power whole system.
· Project still has potential for improvement. By installing GPS, trajectory tracking can be realised.
Designing Optical Fibre Backbone Network-2022
· Working with two people to design optical fibre network from Melbourne to Sydney with adding-drop point at Albury and Canberra.
· Mainly responsible for route arrangement and selecting components that meet design requirements such as fibre, EDFA and transceiver.
· Through MATLAB scripts for simulating a QPSK link, optimal parameters will be found according to simulated result. Then using these parameters in practical testing, BER will be 0.0012 which is smaller than threshold (0.004).
Barcode scanner-2018
· Working in three people group to design barcode scanner by using JavaScript
· Whole project is divided into two parts, first part is to use camera to identify characteristics of barcode (such as gap between black and white stripes, etc.).
· mainly responsible for second part which is to take obtained characteristics of barcode and convert them into actual numbers.
· Checking system is designed to compare scanned check digit with theoretically calculated values. If they match, then display will be correct. If they do not match, second scan is performed until correct result is obtained.
· Finally, according to experiment, designed barcode scanner can accurately scan barcode of product and get accurate digital code.
