Abstract
An integrated sensing device comprising a force sensor and fingerprint sensor disposed on different portions of a flexible circuit. The fingerprint sensor is disposed on a first side of a first portion of the flexible circuit and the force sensor is disposed on a second portion of the flexible circuit. The flexible circuit is configured such that the first portion is over the second portion. The fingerprint sensor includes fingerprint sensor electrodes disposed on the first side of the first portion. The force sensor comprises a compressible layer disposed between a second side of the first portion and a first side of the second portion, and one or more one force electrodes.
