ALBUQUERQUE, N.M. — Every over-the-counter medication bottle sports a protective seal, usually a plastic wrap or foam layer, or both. These seals offer signs of tampering attempts. In a parallel concern, the International Atomic Energy Agency relies on tamper-indicating devices to make sure it knows if containers of nuclear material have been opened or tampered with.

However, just as a medication bottle might be opened and the tamper seals carefully reattached by a bad guy, the IAEA is concerned its devices could be bypassed and repaired or counterfeited. A possible solution? Engineers at Sandia National Laboratories have developed a groundbreaking prototype using “bruising” materials. Their innovation doesn’t just detect tampering; the new device boldly displays the evidence, like battle scars.
