BAC­TE­RIAL BAT­TER­IES

BBC Earth (Asia) - - Science -

Mi­nus­cule cur­rents caused by the move­ment of bac­te­ria could one day be used to power nanoma­chines or tiny elec­tri­cal com­po­nents, ac­cord­ing to sci­en­tists from Ox­ford Univer­sity. The team, from the univer­sity’s de­part­ment of physics, found that dense so­lu­tions of swim­ming bac­te­ria will spon­ta­neously or­gan­ise around tiny ro­tors, form­ing a mi­cro­scopic ‘wind­farm’. Swarm-like ac­tiv­ity within this ‘liv­ing fluid’ drives the ro­tors, pro­vid­ing a tiny but steady source of power that could be used to run the next gen­er­a­tion of mi­cro­ma­chines, nanobots or smart­phone com­po­nents.
