Capacitive biopotential measurements are susceptible to motion-artifacts (MA) due to the non-contact property of capacitive electrodes. Among the methods used to reduce MA, the two proposed by Serteyn et al. and Heuer et al. are based on analyzing the time domain behavior of the measurement system. Serteyn's method only partially reduces MA, while Heuer's method can completely remove MA with a reconstruction equation. However, it has not been investigated to what extent Heuer's method can tolerate the inaccuracies in the parameters of the reconstruction equation. This is why we performed a sensitivity analysis on Heuer's method using dynamic simulations in MATLAB with different inaccuracies added to the known reconstruction parameters. The results were compared to those of Serteyn's method, showing that Heuer's method becomes inferior to Serteyn's method at a lower inaccuracy of parameters when the body static charge is higher.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
