Abstract: A vibrating wire strain gauge capable of measuring strains in concrete elements to an accuracy of better than 0.5 μɛ is presented. This offers some advantages over conventional electrical resistance gauges, the quoted accuracy of which is typically 3 μ ɛ, and which are often considered unsuitable for concrete because of their inability to span cracks.

Re: low tech concrete vibrator James, one could hold the vibrating head against the outside of the form and move it from the bottom to the top and probably get some effect. Or strap the head to the form using pipe clamp brackets in which case the effect would be to have the form and the head vibrate as one and that I expect would work better.
