Innovative Evidence: From Lab to Wrist with Loss-of-Pulse Detection. With Dr Jake Sunshine- Research Scientist at Google

Annabelle speaks with physician-scientist and Google research lead Dr. Jake Sunshine about bringing loss-of-pulse detection from research concept to a regulated feature on consumer wearables.

Jake shares the journey from early laboratory experiments to real-world deployment, and how his team designed an evidence strategy where no clear playbook existed—combining simulation, opportunistic clinical validation, and early regulatory engagement. It’s a powerful reminder that innovative technologies often require equally innovative approaches to generating evidence.
