CN0350 for Piezo strain

Dear all:
Thanks for all your reply.
I may not write my demand clear.
My application is not using strain gauge, instead, i want to use piezoelectric sensor, such as MFC, PVDF, or PZT to measure the dynamic strain.
We are considering the Figure 2. Charge Input Signal Conditioning Circuit In CN0350 without using the AD7091R.
However, our question is
1. The Charge Input Signal Conditioning Circuit In CN0350 seems designed for acceleration, we don't know if it also fit the strain measurement? and how to modify it for strain measurement.
2. The CN3050 mentions that "The AD8608 is chosen for this application because of its low bias current (1 pA maximum), low noise (12 nV/√Hz maximum) and low offset voltage (65 μV maximum). Power dissipation is only 15.8 mW on a 3.3 V supply. ". However, the 15.8 mW Power dissipation on a 3.3 V supply is higher. If it is possible to find others to replace the AD8608 for lower Power dissipation? (close to or Below 1mW ).

Thank you so much.
