چکیده انگلیسی
Pyroswitches and circuit breakers play an important safety role in electrical systems. A miniature one-shot circuit breaker based on the violent reaction of a nanothermite is presented for safety application as protection against overcurrent, external perturbation and short circuit of a broad range of equipment and systems. This device consists of two circuits assembled together to define a cavity. An ignition chip is placed into this cavity and ignites, within less than 100â¯Î¼s, a few milligrams of nanothermites powder. The resulting violent reaction interrupts a thick copper connection within 1â¯ms. After the presentation of the device design, fabrication and assembly, we demonstrate the good operation and reproducibility of the device (100% of success rate) with a response time much lower than that of classical mechanical circuit breakers, which are slow. The response time can be tuned from 1.02â¯ms to 0.57â¯ms just by adjusting the mass of nanothermites from 5.59 to 13.24â¯mg, i.e., adjusting the volumetric solid loadings from 5.6 to 19%. The nanothermites-based circuit breaker presented in this paper offers unprecedented advantages: it is built using only safe substances and is based on a low-cost mass fabrication process that is compatible with electronics. The proposed concept is generic and can be applied to a large number of applications (electrical storage, aerospace manufacturing, human safety, demolition parachute opening, road vehicles, battery powered machinesâ¦).
