Abstract

This paper presents a safe, affordable, and noninvasive approach to estimate subcutaneous fat thickness by using a multi-distance near infrared (MD-NIR) interactance-based wireless sensing platform. In order to perform the simultaneous measurements at several distances, two light sources with different wavelengths are located at one end of a line followed by seven photo diodes. Bluetooth Low Energy are adopted as their primary communication protocol as a wireless communication. The measured data from the MD-NIR interactance sensors are wirelessly transmitted to a smartphone or a tablet for analysis. The feasibility of the approach and wireless platform is demonstrated using the ex vivo pig fat layer phantoms.
