Smart holograms to be used as medical sensors

A company with roots in Cambridge University is working to develop "smart holograms" that can be used as sensors to detect everything from blood-glucose levels to food freshness. The company, aptly (if not creatively) called Smart Holograms, has already produced a prototype contact lens that can be used by diabetics to track their sugar levels, as well as a patch that can read a person's blood-alcohol level. The holograms work by incorporating polymers that swell or contract on contact with specific chemicals or biological agents. As the polymer's shape changes, embedded images can be altered as well, providing a visual readout.
