    "body_text": "The sensor begins as silver-coated yarn wrapped in a flexible polymer, then changes behavior when the yarns are twisted into one-, two- and four-layer architectures. In the reported measurements, more layers increased maximum load, elongation and pressure sensitivity; the four-layer design reached 0.1331 per megapascal at 100 kilohertz, stayed stable through 15,000 cycles and showed little thermal drift from 25 to 90 degrees Celsius.\n\nThe trade-off ran in the opposite direction for proximity: the reported detection range narrowed from 60 millimeters for one layer to 40 millimeters for four. A small textile array mapped contact, and a robotic-arm integration reacted to touch and proximity with 403-millisecond end-to-end latency. The work is a laboratory characterization of one materials platform, not evidence of general-purpose synthetic skin, but it makes the yarn architecture itself a practical design variable.",
