Abstract
A capacitive coupling based sensor is disclosed. In some embodiments, a sensor comprises a transmitter and a receiver that are configured to be capacitively coupled when a coupling condition is satisfied as well as a circuit configured to determine whether a received signal that is received by the receiver matches a transmitted signal that is transmitted by the transmitter.
