Type 1: Type 1 diabetes iswhen there is noinsulin in the body. Italso tells about thepancreas and on howbeta-cells produce.because of this. Thisnormally leads toincreased blood andurine glucose.

10

Type 2: Type 2 Diabetes is

when the body cells fail to

respond properly to the

insulin. This is normally

occurred because of the

reduction of exercise or an

non-balanced diet.

Insulin delivery is a completely different issue with Glucose monitoring

but it always need to monitor the Insulin levels in blood.

First Step is Fabrication of Mold, I selected SU8 and PUMA

Resin as mold material, extracting timing is under

progress now.

28

The attention of SU8 to Silicon substrate is not

enough to remain structure after develop step and

rinsing.
