Notes:
- The response point marks the pivotal moment when the pressure exerted on the sensor begins to gradually rise from 0. At this juncture, the sensor’s resistance declines to a level below 1MΩ, a clear indication of the sensor’s activation and the commencement of its responsive behavior.
- The difference between devices and batches is evident. Usingg a program algorithm, the consistency error can decrease by ±15%. This guarantees a higher level of uniformity and accuracy across the devices.
