Comparison of the parameters of the optimal FSD sensor combination (#34,457) with those of the previously published FSD sensor from the study of Liu et al. (1998)

	Zm,F	τm,F	Zh,F	τh,F	Zm,S	τm,S	Zh,S	τh,S	Zm,D	τm,D
Opt. FSD	50	10−4	30	10−2	40	10−3	10	10−2	10	10−1
Prev. FSD	14.2	5 × 10−4	9.8	1.5 × 10−3	7.2	5 × 10−2	2.8	6 × 10−2	3	5 × 10−1

All Z values are in nanoamperes per nanofarad, and all τ parameters are in seconds. Opt. FSD, Optimal FSD sensor; Prev. FSD, previously published FSD sensor.
