(OP)
Could anyone suggest how to make the electrical strain gage by our own without buying from manufacturer.? Any source on the web.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: electrical resistance strain gage
To manufacture one, a length of very fine conductive wire is required. This has to be laid out in a 'zig-zag' (like a multiple 'S' but with numerous back and forth wires. This permits a length of wire to be placed in a much shorter length. This is where the bigger problem will occur because the bends in the wire are at the ends, where there is little strain; bending the wire increases the resistance. This wire assembly must then be transferred to the object being tested. As a guess, the area on the tested object can have a 'glue patch' and the strain gauge can be transferred on adhesive tape. It won't be an easy undertaking.

When performing an evaluation using strain gages there is no substitute for quality gages, and today's suppliers produce extremely accurate gages. I would expect that most people could not get anywhere near the same level of quality, and any "home-made" gages would result in too much background signal noise to have much use.
