Dropped S$50 last night, ordering four strain gauges for use in our EE2001 project. I'm intending to use these to measure a person's weight. The free shipping was surprisingly fast, as they arrived this past afternoon.

At S$11.90 + GST a pop, these things are quite pricey! I'm just not sure what the tiny yellow pad with two contacts and green line are. But the thin red ribbon-looking component is the strain gauge.

Some how, my electrical design project has taken on mechanical aspects. Will be needing to break out mechanics of deformable solids formulas in order to determine what kind of material and design I should rig these strain gauges on to.
