A skin-strain-actuated microfluidic pump (SAMP) is provided that utilizes asymmetric aspect ratio of pumping channels for the recording of human activity in the fluidic domain.
Equipment used
A Biomomentum MACH 1 applied cyclic uniaxial tensile strain to fabricated PDMS microfluidic pump chips during benchtop characterization. Liquid-interface positions were measured from images to evaluate pumping efficiency and liquid displacement against strain amplitude and actuation count. Human movement and shoulder DIC experiments were separate.
