A biomedical implant includes a wall enclosing at least a portion of the implant. The wall includes a first stratum and a second stratum conformal with the first stratum. An interlayer is provided between the first and the second strata, and includes a structure that produces capillary pressure in an infiltrating fluid in response to rupture of the first stratum or the second stratum resulting in entry of the infiltrating fluid into the interlayer. A detector is exposed to the interlayer and configured to detect a presence, if any, of the infiltrating fluid and output a detection state indicator. A communication circuit is communicatively coupled to the detector and configured to communicate the detection state indicator to a reader external to the patient.
