NIST researchers demonstrated an approach for detecting hidden flaws in ceramic capacitors, which store energy in the electronics for medical implants and spacecraft. NIST studied 3-millimeter-long capacitors (top photo), looking for cracks similar to the one shown in the NASA photo (bottom). Credit: NIST/NASA
Medical implants and spacecraft can suddenly go dead, often for the same reason: cracks in ceramic capacitors, devices that store electric charge in electronic circuits. These cracks, at first harmless and often hidden, can start conducting electricity, depleting batteries or shorting out the electronics...
