Seebscribe
My Heartbeat

The heart doesn't just pump - it broadcasts. Every beat sends a pressure wave through the entire body, readable by an optical sensor as a flickering shadow in the fingertip. SEEBSCRIBE captures that signal and makes it shareable: a wearable device worn on the chest that reads your heartbeat and transmits it, live, to anyone who subscribes to your signal. Not your content. Your body.

The name collapses three ideas. See - making the invisible visible. Subscribe - the internet act of following someone's output, reimagined as following someone's autonomic state. And SEEBECK - Thomas Johann Seebeck, who discovered in 1821 that a temperature difference between two conductors generates voltage. That is the physics of the power source in this device: body heat converted directly into electricity through a thermoelectric chip. The device is powered by the fact that you are alive and warm. It stops working when you do.

What a subscriber receives is richer than a number. Heart rate variability - the subtle irregularity between beats - encodes stress, calm, focus, and emotion with medical precision. The waveform itself is a fingerprint: no two people's pulse signals look exactly the same. SEEBSCRIBE asks what it would mean to sync two hearts across distance - light pulsing in someone else's room to the rhythm of your chest, a haptic tap in their wrist timed to your breath. The body as the most honest signal you can share.
