Technically, I’m quite confident that Sniphi could recognize the smell of poo. The bigger challenge would be the environment inside a cleaning robot — dust and particles could interfere with the sensors. I believe this could be addressed with some engineering effort, for example using filtration or protective sensor covers, but it would require additional work.
That’s why we are also looking at some lower-hanging applications. For example, in nursing homes or hospitals. A bedridden patient with a diaper that isn’t changed in time can develop serious complications — especially elderly patients, where infections can become life-threatening. In that context, a “sneaky poo detector” could actually improve care and potentially save lives. Do you know anyone who might be interested in partnering with us to test this idea?
Independent of the sensor smelling, I am recently curious if there are smell libraries where I myself could better learn to classify scents. Recently I came across a laundry detergent scent that was great but I didn't get the brand name and now I can't explain what it smelled like.
