The invention relates to a flexible, resilient capacitive sensor suitable
for large-scale manufacturing. The sensor comprises a dielectric, an
electrically conductive detector and trace layer on the first side of the
dielectric layer comprising a detector and trace, an electrically
conductive reference layer on a second side of the dielectric layer, and
a capacitance meter electrically connected to the trace and to the
conductive reference layer to detect changes in capacitance upon
interaction with detector. The sensor is shielded to reduce the effects
of outside interference.
