The Traverso Lab is building a flexible sensor system that uses electrical current to measure mechanical pressure in the gastrointestinal tract. Such a device could assess disease-associated dysfunction in the contracting muscles that move and break down food during digestion.

Researchers are looking for just the right amount of stiffness, conductivity, and adhesion…and above all, consistency. With nearly 100 sensors working in tandem across the system, it is essential that every measurement be comparable, accurate, and precise.
