Abstract
A force input control device suitable for high-volume applications such as cell phones, portable gaming devices and other handheld electronic devices along with other applications like medical equipment, robotics, security systems and wireless sensor networks is disclosed. The device can be one-axis or two-axis or three-axis sensitive broadening the range of applications. The device comprises a force sensor die formed within semiconductor substrate and containing a force sensor providing electrical output signal in response to applied external force, and electrical connection elements for mounting and/or wire bonding. Signal conditioning and processing integrated circuit can be integrated within some devices. A package enclosing at least a portion of the force sensor die and comprising a force-transferring element cooperated with the sensor die for transferring an external force to the force sensor die.
