Paper Abstract

A palm-size interdigital impedance sensor incorporating a 10 μL sample reservoir, temperature sensor and hybrid heater was fabricated to determine the feasibility of measuring macronutrients in ultra-small volumes of human breast milk. Comparisons with previous measurements of homogenized cows milk show excellent agreement with fat measurement. Human breast milk however shows no correlation with fat but a surprising correlation with protein. Our investigations and proposed methods to improve the correlation and measurement accuracy are discussed.
