Sensitive pad..

I just had a random conversation with my senior this afternoon in class..He's from DM too..He did ask me about my FYP,what am i doing for my FYP..So i said that i'm doing something about water therapy..And he asked me how it's going to work,and how am i going to make it happens..I said that i'm not really sure about that..I told him that i wanna use sensitive pad to detect the sound..And he said,that thing will be a little bit expensive and it's quite hard to find..I'll try my best to make it happen! :)


Maybe i'm going to use something similar to this,but smaller version of it..

Sincerely,
ALIA
