摘要： The present invention provides a sensor system and a corresponding sensing method employing the sensor system. The sensor system comprises a sensor (12) having an input (20) and an output (22), a feedback path (16) from the output to the input, and a filter (14; 92) in the feedback path. The filter comprises a narrow band filter, which is tuned or tunable to a respective one of signals that are wanted signals and signals that represent interference signals. The sensor and the filter are arranged so as to alter the relative amplitudes of the wanted signals and the interference signals in order to increase the relative amplitude of the wanted signals and reduce the relative amplitude of the interference signals.

摘要： The present invention provides an electric potential sensor (28) for the measurement of potentials non-invasively. The sensor comprises at least one detection electrode (12) arranged for capacitive coupling with a sample under test and for generating a measurement signal, and a sensor amplifier (14) adapted to receive the measurement signal as input and to supply an amplified detection signal as output. Input impedance enhancing means (12a, 32, 36, 38, 44) are included for providing a high input impedance to the sensor amplifier for increasing the sensitivity of the electrode to reduced electric potentials, and a discrete pre-amplifier stage (30) is arranged to co-operate with the sensor amplifier to reduce the input capacitance of the amplifier.
