Table 5 Features extracted from sensor response curves.

A

\(C= \frac{{R}_{during}}{{R}_{0}}\)

B

\(\delta = {R}_{during}- {R}_{0}\)

C

\(\delta = {R}_{after}- {R}_{0}\)

D

Minimum value of resistance reached during the measurement (R_min)

E

\(DR= \frac{{R(t}_{3})- {R(t}_{2}) }{{R(t}_{2})-{R(t}_{1})}\)

F

\({LD=R(t}_{2})- {R(t}_{1})\)

G

\(y\left[k\right]=\left(1-\alpha \right)y\left[k-1\right]+ \alpha (x\left[k\right]-x\left[k-1\right])\)

H

R₀/R_min
