Sensors

Hi folks,

I'm a newbie in electronics subject (or even worst than newbie), and i have one questions to a personal project of mine...:

Someone knows if there are in the market (and in case of positive answer please give me the link of one), one sensor to measure the abdominal perimeter, or in other words, like a elastic belt who measure the length of the belly or of the ballon (but is to measure all the time... so must be a sensor to retrieve the length/perimeter);




Thks :smile:
