SQUID handcuffs

Abbreviation for Superconducting Quantum Interference Devices handcuffs. A pair of handcuffs containing SQUID materials placed inside superconductive pieces of metal. SQUID handcuffs are comprised of 2 metal bracelets connected by electricity, and are capable of detecting the subtle changes in the human body's magnetic field brought on by mental processes such as emotional stress. Their selling point is the ability of their connection to adjust to the wearer's mental state.

This is the type of handcuff used by BCP.
