WEEK 8: DESIGN PROJECT BLOCK DIAGRAM

In the process to develop non-invasive blood glucose monitoring system, it is divided into several main parts. To analyse and predict glucose concentration, it is possible by using glucose spectroscopy between wavelength 1100nm to 2450nm. The system setup consists of a reflective optical sensor, for transmission and reception of NIR rays with the fingertip as the body site. NIR signals are passed through the fingertip and detected photodiode. Then photodiode current output will convert into voltage signal by current to voltage converter. After that, the output will filter and amplify using high pass filter, low pass filter, noise filter and amplifier before conditioned for better result. The output is then fed to microcontroller unit to process the receiver signal and performed voltage variation analysis as to monitor whether the obtained value is within threshold.

WEEK 7: ARDUINO

Arduino UNO

The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins, 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller. I proposed to use arduino as my microcontroller for my project.

WEEK 6: SECOND FYP BRIEFING

Date: 9th November 2016

Venue: TTL1 (GO4)

Time: 3pm-4pm

Second briefing was held to give information and overview about proposal report writing. Proposal report which is carry 35% from this subject. From the briefing also we learnt guideline to write a technical proposal. This proposal includes abstract, introduction, literature review, methodology and conclusion. 

WEEK 5: NEAR-INFRARED

Detection of Glucose Level Using Non-Invasive Method project involves the use of near-infrared (NIR).

so, I'll explain about NIR today.

The NIR defines the range of wavelengths from 650nm to 2500nm where light has its maximum depth of penetration in tissue. Within the NIR, scattering is the most dominant light-tissue interaction, and therefore the propagating light becomes diffused rapidly. Since scattering increases the distance traveled by photons within tissue, the probability of photon absorption also increases. Because scattering has weak dependence on wavelength, the NIR is primarily limited by the light absorption of blood at short wavelengths and water at long wavelengths.
