BREACH SENSOR

摘要

One example discloses a breach sensor (100), comprising: a substrate (104) including an integrated circuit; a passivation layer (106) coupled to the substrate; a breach sensing element (108, 110) coupled to the circuit; wherein the breach sensing element is on a first side of the passivation layer and the substrate is on a second side of the passivation layer; a barrier (112) configured to separate the breach sensing element from an ambient environment; wherein the breach sensing element is responsive to barrier damage.
