Abstract: Integrated systems for force or strain sensing and haptic feedback are described herein. An example force-haptic system can include a sensor chip configured to receive an applied force, where the sensor chip includes at least one sensing element and an integrated circuit. The force-haptic system can also include a haptic actuator configured to convert an electrical excitation signal into mechanical vibration. Further, the force-haptic system can include a circuit board, where the sensor chip and the haptic actuator are electrically and mechanically coupled to the circuit board. The integrated circuit can be configured to process an electrical signal received from the at least one sensing element and to output the electrical excitation signal.

Abstract: Described herein is a MEMS force sensor with stress concentration design. The stress concentration can be performed by providing slots, whether through or blind, and/or selective thinning of the substrate. The MEMS force sensor is in chip scale package with solder bumps or metal pillars and there are sensing elements formed on the sensor substrate at the stress concentrate area. The stress concentration can be realized through slots, selective thinning and a combination of both.

Abstract: An example force sensitive touch panel device can include a device body; a touch surface for receiving a touch force; a sensor for sensing touch force that is arranged between the device body and the touch surface; and a membrane configured to mechanically isolate the device body and the touch surface. Additionally, the membrane can apply a preload force to the sensor.
