Cottage Industry
Estate agents are known for describing smaller houses as ‘bijou’ or ‘cosy’. But imagine the tiny clunks of roof panels slipping together in this house, a million times smaller than a cottage. Pictured with a scanning electron microscope, the tiny abode is assembled by robots on the tip of an optical fibre (looking like a podium here), inside a nanofactory. An ion beam laser cuts a template of the house out of a sheet of silica ‘paper’, which then folds itself up. A tweak on the laser settings welds the house together. But this isn’t a rehousing project for bacteria, rather a proof of principle for an even more ambitious idea – constructing tiny, yet sophisticated sensors on the ends of optical fibres as thin a human hairs. At home inside the body, these could measure our blood pressure, changes in temperature or the monitor the fight against infections.
