O tema da extra\u00e7\u00e3o de eletricidade do \"ar\" \u2015 a partir de ru\u00eddo eletromagn\u00e9tico, vibra\u00e7\u00f5es, luz, umidade e muitos outros fatores \u2015 interessa tanto a pesquisadores civis quanto a seus colegas fardados. Sua contribui\u00e7\u00e3o para este tema foi feita por cientistas<\/a><\/noindex> da Universidade Estadual da Pensilv\u00e2nia. A partir dos campos magn\u00e9ticos das fia\u00e7\u00f5es pr\u00f3ximas, eles conseguiram gerar eletricidade com pot\u00eancia de alguns milivolts, o que \u00e9 suficiente, por exemplo, para alimentar um despertador digital.<\/p>\n

\"Americanos<\/p>\n

Em um artigo publicado na revista Energy & Environmental Science<\/a><\/noindex> os cientistas discutiram os c\u00e1lculos e a fabrica\u00e7\u00e3o de conversores especiais de campos eletromagn\u00e9ticos em corrente el\u00e9trica. O elemento extrator \u00e9 feito na forma de uma l\u00e2mina fina em m\u00faltiplas camadas com um \u00edm\u00e3 permanente na extremidade livre (a outra extremidade da l\u00e2mina est\u00e1 firmemente presa). A pr\u00f3pria l\u00e2mina consiste em uma camada de piezoeletricidade e uma camada de material magnetoestrictivo<\/a><\/noindex> (Fe85B5Si10 Metglas).<\/p>\n

O material magnetoestrictivo \u00e9 interessante porque, ao alterar o estado de magnetiza\u00e7\u00e3o, seu volume e dimens\u00f5es lineares mudam. O barulho irritante das bobinas nas placas de v\u00eddeo \u00e9, na verdade, altera\u00e7\u00f5es magnetoestrictivas nos n\u00facleos. Em um campo magn\u00e9tico alternado de uma fia\u00e7\u00e3o comum com frequ\u00eancia de 50 ou 60 Hz, a l\u00e2mina de Metglas come\u00e7a a vibrar e deforma a l\u00e2mina de piezoeletricidade colada a ela. A corrente come\u00e7a a fluir na rede conectada \u00e0s l\u00e2minas.<\/p>\n

\"Americanos<\/p>\n

No entanto, o material magnetoestrictivo em conjunto com o piezoel\u00e9trico gera apenas at\u00e9 16 % da eletricidade gerada pelo elemento. A maior produ\u00e7\u00e3o vem da oscila\u00e7\u00e3o de um \u00edm\u00e3 permanente em um campo eletromagn\u00e9tico. Afirma-se que a tens\u00e3o de pico no elemento atinge 80 V em um campo de 300 \u00b5T. Mas o mais valioso \u00e9 que o elemento desenvolvido podia gerar energia suficiente para alimentar diretamente rel\u00f3gios digitais em um campo de menos de 50 \u00b5T a uma dist\u00e2ncia de 20 cm da fia\u00e7\u00e3o el\u00e9trica.<\/p>\n

Sua pesquisa foi conduzida por cientistas da Universidade Estadual da Pensilv\u00e2nia em conjunto com pesquisadores da Virginia Tech e do grupo de Comando de Desenvolvimento de Capacidades de Combate do Ex\u00e9rcito dos EUA.<\/p>\n
