This disclosure provides systems, methods and apparatus for a combined sensor device. In some implementations, a combined sensor device includes a wrap-around configuration wherein an upper flexible substrate has patterned conductive material on an extended portion to allow routing of signal lines, electrical ground, and power. One or more integrated circuits or passive components, which may include connecting sockets, may be mounted onto the flexible layer to reduce cost and complexity. Such implementations may eliminate a flex cable and may allow a bezel-less configuration.
