Smart jail cells could predict and prevent inmate violence

Abstract:
Holding cells fitted with specially-adapted sensors could provide early warnings if inmates become agitated or have a medical emergency, reports Marina Murphy in Chemistry & Industry magazine.

The sensors are made of a nano-modified polymer film. A high-pressure gas expansion system is used to introduce microscopic bubbles into the film, which is then charged and fitted with electrodes.

Changes in the film thickness, caused by footsteps or the force of a breath, produce an electrical charge that can be measured.
