Methods and systems for monitoring a well-being of a target are disclosed. In a method embodiment, data representing a process electric potential signal is received by a computer system. The process electric potential signal may be generated at least in part by one or more electric potential sensors in response to the detection of a change in an electric field of a target spaced apart from the one or more electric potential sensors. The method may further include identifying, using the computer system and based at least in part on the data electronically received by the computer system, a recurring pattern in the received data. The method may also include determining, using the computer system and based at least in part on the received data, whether a deviation from the recurring pattern transgresses a threshold. The deviation may comprise a subset of the data electronically received by the computer system.
