Spark Biomedical partners with Battelle and Hazelden Betty Ford to develop an AI algorithm for detecting opioid withdrawal symptoms and cravings, funded by a $318,875 SBIR grant from NIDA. Phase I focuses on data collection and AI algorithm development, while Phase II aims to integrate the algorithm with Spark's FDA-cleared tAN® device, Sparrow® Ascent, for closed-loop neurostimulation treatment.
