The proposed device, with a theoretical operating energy budget less than 10 attojoules, uses a differential architecture to compensate for environmental variations and the device can retain sensed information for durations ranging from hours to days.
A new way to arrange very small materials with perfect control could lead to more secure banknotes and passports, and quicker detection of harmful gas through a clever use of light.
Researchers have used experiments and simulations to find out by what means MOFs can be rendered flexible and why: they tricked the system by using clever chemical manipulations to enable a variety of energetically similar arrangements in the crystalline order.
