A decade inside Singapore's healthcare infrastructure

A bathroom visit that usually takes fifteen minutes stretches to forty.

In a home with no sensors, no one notices until the next phone call, the next visit, the next time someone thinks to check. In a home instrumented with motion sensors tracking daily patterns, that deviation is flagged in real time.

Not because of complex AI. Because of sustained observation of one life, in one home, over enough time that the system knows what normal looks like.

In 2012, a small team in Singapore started placing recycled smartphones in the hands of underserved seniors. By 2016, the system had evolved into a full IoT deployment across hundreds of homes as part of the national Smart Nation programme. Motion sensors in every room. Door contacts on the front door. Thousands of data points per household per day.

The technology worked. What broke was everything around it.

Tomorrow: the full story of that decade, and what it taught about building healthcare infrastructure at national scale.
