摘要:
Provided are multiple normal stress detection sensor units 300 capable of detecting a normal stress, and a sheet layer portion 200. The sheet layer portion 200 includes an exterior sheet layer portion 210, a force detection sheet layer portion 230 incorporating normal stress detection units 300, and an intermediary layer 220 sandwiched between the exterior sheet layer portion 210 and the force detection sheet layer portion 230. The exterior sheet layer portion 210 and the force detection sheet layer portion 230 include multiple protrusions 212 and 232 protruding in directions opposed to each other, and are disposed such that the protrusions 212 and 232 engage each other with the intermediary layer 220 interposed therebetween. Each normal stress detection sensor unit 300 includes a central portion detection sensor device 310 disposed immediately below a central portion of the protrusions 232 provided on the force detection sheet portion 230, and at least two edge detection sensor devices 321 to 324 disposed immediately below edge portions of the protrusion 232 provided on the force detection sheet portion 230.

A touch sensor system 100 includes buses 110, a plurality of touch sensor devices 200 disposed on the buses 110, and an information integrating device 140 that is connected to all the buses 110 and integrates information from the touch sensor device 200. The touch sensor device 200 includes a sensor unit and a signal processing unit that transmits a sensor data signal generated by processing an analog sensor signal to the information integrating device through the bus. The signal processing unit includes a digital converting unit, a threshold evaluating unit that gives a start permission of the signal process when a sensor value exceeds a preset threshold, an ID adding unit that adds a transmitter identification number to the sensor signal, and a data transmitting unit that outputs the sensor data signal to a signal line of the bus. Fast responses are made possible without increasing the amount of data and host processing load while including many touch sensor elements.

摘要:
Provided is a technique for packaging a sensor structure (300) having a contact sensing surface and a signal processing LSI (420) that processes a sensor signal. The sensor structure (300) has the contact sensing surface and sensor electrodes (320, 330). The signal processing integrated circuit (420) is embedded in a semiconductor substrate (400). The sensor structure (300) and the semiconductor substrate (400) are bonded by a bonding layer (500), forming a sensor device (200) as a single chip. The sensor electrodes (320, 330) and the integrated circuit (420) are sealed inside the sensor device (200), and the sensor electrodes (320, 330) and external terminals of the integrated circuit (420) are led out to the back surface of the semiconductor substrate (400) through a side surface of the semiconductor substrate (400).
