Abstract

A method to fabricate a tamper respondent assembly is provided. The tamper respondent assembly includes an electronic component and an enclosure at least partly enclosing the electronic component. A piezoelectric sensor is integrated in the enclosure. The integrating includes providing a base structure that includes a first conductive layer, depositing a piezoelectric layer on the first conductive layer, covering the piezoelectric layer with a second conductive layer, and providing sensing circuitry for observing sensing signals of the piezoelectric layer. The piezoelectric layer includes a plurality of nanorods. Aspects of the invention further relates to a corresponding assembly and a corresponding computer program product.
