20. Similar to the example 2.2, Design a respiratory sensor that uses a strain gage (Bus) within a chest strap is implemented as a part of Wheatstone bridge. It counts a breath whenever the output voltage from the strain gage circuit triggers a comparator (with no hysteresis) to toggle its output from low to high during inhalation. The strain gage is made of p-type Germanium. Assume that the change in the length of the strain gage from complete exhalation to complete inhalation is 110% (in other words, length increases by 10%), and the resistance of the strain gage at full exhalation is 28 and the R3 is 2 k. For this problem, you need to provide the calculation process to show what resistance you choose for R1 and R2. (10pts) Vec Ri R; 2K UI MM B . VOUT LT1632 R2 Ros 2K ► Lan 0 1 0 0.1
