Vagustim v2 Review: AI-Powered tVNS Wearable Revolutionizes Biohacking

As a product engineer who lives and breathes wellness tech, I have to say the Vagustim v2 crowdfunding campaign immediately grabbed my attention. The premise is a masterclass in modern biohacking: a consumer-grade wearable that leverages transcutaneous vagus nerve stimulation (tVNS) to help regulate the body's "rest and digest" functions. It’s a bold vision, and diving into the technical architecture reveals some genuinely clever engineering choices.

Let’s start with the core innovation: the AI-driven personalization. This isn't just a device with preset programs. The system claims to use a closed-loop feedback mechanism. This is a huge leap! Imagine a wearable that doesn't just broadcast a signal, but actively listens to your body's response through biometric sensors—likely focusing on...
