In this episode of The Open Loop, Chay Carter is joined by Daniel Powell, Founder of Spark Biomedical.

Daniel shares his journey from consulting into more than two decades in neuromodulation, with experience across spinal cord stimulation, DBS, vagus nerve stimulation, and non-invasive auricular neurostimulation.

This is a practical conversation about building clinically validated neurotechnology and taking one platform into multiple high-need areas.

We explore Spark Biomedical’s work across opioid withdrawal, surgical blood loss, and women’s health, as well as the challenges of reimbursement, clinical evidence, form factor, and scaling wearable neuromodulation into real-world care.

Key takeaways:

🔹 How Spark Biomedical is using auricular neurostimulation across multiple clinical applications
🔹 Why opioid withdrawal is a powerful but commercially challenging indication
🔹 How the “neural tourniquet” could help reduce blood loss in surgery and trauma
🔹 Why OhmBody is applying neurostimulation to heavy menstrual bleeding and women’s health
🔹 Why clinical evidence matters as wearable neurotechnology becomes more accessible
