| An electronic field that is intended to shield living tissue from a Life Detector. |

In the real world, there are various ways to detect the presence of living beings (most of them don't differentiate that well between animals and people). For example, there are sensors that will detect the presence of carbon dioxide, which we all give off when breathing. And there are infrared sensors, which detect our body heat.
Compare to the life-shield blanket from Heretics of Dune (1984) by Frank Herbert, the
radiant shield from The Houses of Iszm (1954) by Jack Vance, the
protective shield from Triplanetary (1934) by 'Doc' Smith and the
personal force-shield from Foundation (1951) by Isaac Asimov and the geofractor shield from One Against the Legion (1939) by Jack Williamson.

As far as the future is concerned 'they're the only experts we have'.
'The walls and ceiling bore an irregular spacing of illuminum tiles...'
'The planes flew continuously, twenty-four hours a day...'
'It was even conceivable that they watched everybody all the time.'
