These Smart Walls Can’t Talk, But They Definitely Can See

Using layers of conductive paint in unique patterns, a research team transformed a wall into a wide-area capacitive sensor and an EM-field sensor.

We think of Interior walls for defining and dividing areas (and providing a place to hang things), but what if they could easily and cheaply be transformed into sensors? That’s what a joint project team from Carnegie Mellon Institute School of Computer Science and the Disney Research Pittsburgh has done, as detailed in a paper presented at the ACM CHI Conference on Human Factorsin Computing Systems.

Their highly readable paper, “Wall++: Room-Scale Interactive and Context-Aware Sensing” provides full details on how they used conductive paint to add a dual-function role to a standard wall, providing a mutual-capacitance sensor for close-range sensing plus an electromagnetic-field sensor for wider-area performance. The result is what they call the Wall++, which can become part of a “smart” infrastructure to sense human touch, detect gestures, and even determine when appliances are in use

From fitness trackers to heart monitors, the IoMT is coming

The Internet of Medical Things, or IoMT

The emerging infrastructure, such as cloud connectivity and platforms as a service, allows the data gathered to be analyzed by medical professionals or even expert AI systems. This can be used to detect the warning signs that often precede a cardiac event. Trend data gathered over longer periods, when compared against larger samples across carefully classified parts of the population, could even lead to much earlier diagnoses of preventable heart conditions. This is the real potential of the IoMT.
