Abstract: A method and an apparatus for detecting a modification of a compound, the modification occurring during a transient period. The method may include: coupling at least one substance portion comprising ferro elastic material to a compound, the substance portion being configured to change a polarization level thereof continuously in response to a strain gradient applied thereto over the a transient period which results in said modification; sensing a physical property of said substance portion affected by the polarization level of the substance portion, due to the modification; and determining, using a computer processor, the modification, based on the sensed physical property of the substance portion.
