Miniature Passive Pressure Transensor for Implanting in the Eye
Abstract
A newly developed method for measurement of intraocular and other physiological pressures consists of a novel displacement transducer contained in a distensible pillbox small enough (3 to 60 μl) to be implanted in the eye of a small laboratory animal. Nothing pierces or even touches the globe. This passive resonant transensor absorbs energy from an oscillating detector coil outside of the animal at a frequency dependent upon the pressure in the eye. Passive operation provides extended life, but limits useful range to less than 10 transducer diameters, which has proved sufficient for intraocular pressure measurement.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
