Development of an AMR-ACB Array for Gastrointestinal Motility Studies

The association between anisotropic magnetoresistive (AMR) sensor and AC biosusceptometry (ACB) to evaluate gastrointestinal motility is presented. The AMR-ACB system was successfully characterized in a bench-top study, and in vivo results were compared with those obtained by means of simultaneous m...

Both AMR-ACB and manometry techniques presented high temporal cross correlation between the two periodicals signals ( R = 0.9 ±0.1; P &lt;; 0.05).
