Therefore, the multiplexer 163 can be utilized to better monitor the plurality of strain gauges 150, so as to more timely know the internal degumming problem of the touch module 110 due to the external force generated by clamping or hanging in the circulation process.
Alternatively, the predetermined time interval may be 0.1-1s, which may be set according to the need of monitoring the strain gauge 150.
