Interesting article. I'm trying to decide whether this device would offer any help in the search for UAPs. Some schools of thought think extra-terrestrial vehicles would distort gravity?Small, cheap gravity gadget to peer undergroundBy Jonathan Webb Science reporter, BBC News 30 March 2016
The sensor itself, in the middle of the gadget, is the size of a postage stamp
UK researchers have built a small device that measures tiny fluctuations in gravity, and could be used to monitor volcanoes or search for oil.
Such gravimeters already exist but compared to this postage stamp-sized gadget, they are bulky and pricy.
The new design is based on the little accelerometers found in smartphones.
To begin with, the team - from the University of Glasgow - tested it by measuring the Earth's tides over a period of several days.
Tidal forces, caused by the interacting pull of the Sun and Moon, not only drag the oceans up and down but slightly squash the Earth's diameter.
"It's not a very big squeeze, but it means that essentially Glasgow - or anywhere else on the Earth's crust - goes up and down by about 40cm over the course of 12-13 hours," said Richard Middlemiss, the PhD student who made the new instrument.
"That means that we get a change in gravitational acceleration - so that's what we've been able to measure."

www.nature.com/nature/journal/v531/n7596/full/nature17397.html SwampRat, As an FYI, myself and another SETV/OSR member, we started promoting the phrase "UAP" in lieu of our original phrase (Carl Sagan's) "AOP" instead of vocalizing 'UFO'; we ran a gravimeter for three years in the hope of detecting flying-saucers. Although we did detect a number of odd non-baseline readings we had no method of co-verification, such as a visual sighting report, etc. So what did we auctually detect? In addition to that, gravimeters are a bit like weight-scales, they only measure accelleration, unlike Kip Thorn's LIGO. I bought the instrument on eBay in 1994, the fellow who was selling it in an estate sale, stuff found in the deceased's garage/lab, did not know what it was and he sold it to me for a mere $35. As for using electronic MEMS accelerometers, I promoted a discussion on the UFO-Updates list several years ago, which did not elicit any response from any of the lists ET scientists, or Bruce Macabee. I have toyed with the idea using accellerometers quite a bit; I believe that they might be useful, however, the so-called 'Binding Force Meter' as I recall the gadget's name, is actually a very rudimentary accellerometer. I designed a 'binding force meter' for a fellow researcher whose name I've forgotten. He was that rock-hunter fellow (wrote a couple of books on rock-hunting) and was the science-teacher for a civilian military school and who found that metal fragment he believed was from the Roswell craft crash. The version I designed for him, included piezo sensor so that he would not be required to watch it continuously, but would allow a PC to both time-stamp and log any detections. Its my opinion that those 'Force Meters' are not sensitive enough, in any-case. No one has ever reported a detection with those type 'instruments' that I have been able to find. However all that may be, at this juncture, I suspect that you could be correct. The unit that you found seems to be very sensitive, and it is fully electronic unlike mine was. I had to add variable-reluctance linear sensors to it to both easily calibrate and to be able to time/graph its output. It originally employed a clock-motor driving an ink-pen on a circular paper-log. It was really junky. Before all the sensor arrays disappeared behind firewalls, there were accelerometer arrays that were operated as sensor elements of the GKIS-Array, which was designed for detecting nuclear-detonations around the world. In the 1980s during one of my scientific engineering contracts I wrote software for the GKIS-Array. Twelve years later, it was in those type data-sets that I perused for many years looking for alien craft transit signatures. Interestingly, I did find a few tantalyzing data correllations using the HAARP RIOmeter sensor data served by the PFRR that closely matched the time-stamp (and Walters' video event activity of those specific sightings) in concordance with the Ed Walters Gulf-Breeze reports written by Bruce Macabee. I know we can find & track them using data-set corollated instrument arrays. People think and claim all sorts of non-sense about HAARP, but not one of them when questioned has been able to personally describe to me how 'it' works or what HAARP actually does. Almost every person so questioned has however, quoted a quack researcher's 'paper' that describes HAARP as being a large 'transistor' stimulated by the HAARP UHV YAGI Array. Hah hah hah. On your gravimeter find photo one can see a MEMS sensor. plutronus
