AB - This paper presents a multi-directional capacitive proximity sensor array based on band-stop filter. The band- stop filter is composed of four decoupled LC resonant circuits, so each stop band is determined by one capacitive sensor and its corresponding lumped inductor, respectively. Therefore, the change in capacitance can be obtained by measuring the change of the notches of the band-stop response. The filter is fabricated into a cubic shape for sensing different directions. Experiment results show that the fabricated sensor can detect objects coming from all four directions simultaneously by measuring the transmission at frequencies near four notches.
