New Yarn Conducts Electricity
sciencehabit writes: Researchers report the creation of an ultrathin, fabric circuit that keeps high conductivity even while bending and stretching as much as yoga pants. The fiber's core mimics spandex, consisting of an elastic synthetic thread—polyurethane—twinned by two cotton yarns. These stretchy strings were then dipped in silver nanoparticles to instill conductivity and then liquid silicone to encase everything. This silver nanoyarn could stretch as much as spandex—500% of its original length—and retain a high conductivity (688 siemens per centimeter), the team reports online this month in ACS Nano. That's 34 times the conductivity and five times the flexibility seen with prior attempts at nanowires made from graphene. The fibers kept high conductivity after being bent 1000 times or wrapped around fingers. The team used their yarn to link light-emitting diodes within foldable plastic, meaning the fibers might serve as flexible wiring in new-age curved TVs, stretchable digital screens, or electronic clothing.
-I'm not sure how much power (as opposed to voltage) tasers put out---
The Internet says "The TASER® devices release an electric current (TASER® C2 - 30 seconds of 50,000 volts at 7 watts, TASER® M26c - 5 seconds of 50,000 volts at 26 watts)". The low wattage makes sense ecause they're powered by 9v batteries.
