Zusammenfassung:A system may include an integrated circuit and a coating at least partially encapsulating the integrated circuit. The coating may include an electrically insulating material at least partially encapsulating an analog circuit. The integrated circuit may be electrically connected to the analog circuit. Additionally, the integrated circuit may be configured to generate an analog electrical signal, transmit the analog electrical signal through the analog circuit to generate a modified analog electrical signal, receive the modified analog electrical signal, and in response to determining that the modified analog electrical signal is sufficiently similar to an expected analog electrical signal, use the modified analog electrical signal as an input to an algorithm performed by the integrated circuit.
