The dirt-detection system, for instance, uses a tiny microphone to detect dirt.
Building on decades of prior research, scientists have mapped the precise circuit in the fruit fly brain that enables the tiny gnat to detect movement in its visual field — an impulse essential to its skill at avoiding swatting hands and other existential threats.
Even an ultrasound scan is not guaranteed to help as a panda foetus is tiny, difficult to detect and develops late.
Soli uses tiny radar units to detect gesture input where other forms of input, like a touchscreen, might be impractical or impossible.
For years, Chad Mirkin, a chemist at Northwestern University in Evanston, Illinois, and colleagues have used tiny metal particles to detect DNA sequences that can signal the presence of anything from cancer cells to the anthrax bacteria.
Spy cameras and hidden skimmers are tiny devices difficult to detect and they can be used to capture your data.
The amount of variance that will be accounted for by variations in a single gene will usually be tiny and difficult to detect except in very large samples.
However, the orientation mismatches caused by dislocations or cracks between different lamellas are too tiny to be detected in the corresponding SAED patterns.
Stainless steel is softer and rougher than Inconel, making it more difficult to detect tiny cracks within the natural imperfections of the steel, Mr. Hartsfield said.
