In a short news release, the Institute of Physics reports that smart holograms, which use materials called hydrogels that shrink or swell in response to local environmental conditions, can be used to monitor many physical conditions than three years ago. These smart holograms could soon be used ‘by diabetics to check their blood-sugar levels, by patients with kidney disorders to check on adrenaline levels or by security forces to detect chemicals like anthrax after a terrorist attack.’ And today, moisture sensitive sensor holograms are used to verify the presence (or absence) of free water in aviation fuel.
