A problem family — different problems, same issues

92 problems across 17 fields

These 92 problems come from ocean monitoring, medical diagnostics, food safety, agriculture, construction inspection, and materials manufacturing. They share one failure: a sensor or measurement that performs well in controlled conditions and degrades in real use. Construction is a large part of the family. Measuring the depth of concrete over rebar, monitoring silica dust, assessing buried pipe, and testing mass timber in fire all face the same gap as medical diagnostics and ocean sensors. An anti-fouling coating on a marine sensor draws on the same surface science as the coating on an implanted glucose monitor.

Your sensor works in the lab. Has anyone tested it where it has to work: in seawater, inside a patient, on a factory floor, or in a field with no electricity?

Ways this family shows up

Chemical and physical sensors. Laboratory-grade sensors that degrade in the field from interference, drift, and fouling
Medical diagnostics. Bedside and clinic tests designed for well-equipped labs that fail where resources are limited
Never validated in the field. Sensors that no independent party has tested in real conditions, so the gap is in the evidence
Measurement for accountability. Measurements needed to prove compliance, qualification, or environmental performance
Measurement inside a process. Sensors that must work inside manufacturing, amid harsh chemistry, high temperatures, and continuous flow
Inspecting what is already built. Testing structures without damaging them: rebar cover depth, buried pipe condition, mass timber fire performance, silica dust exposure
