Measurement of deformation distance of the PMR base powered by contraction force of the dorsal vessel tissue.
(a) Microscopic images of the prototype from the side. The inset shows an enlarged view of the area surrounded by the white rectangle in the main picture. Movies showing the whole prototype and the inset area, respectively, are available as Movies S3 and S4 in the SI. (b) Time course of deformation distance of the base. The graph was obtained by image analysis processing of Movie S4. (c) The model to estimate the contractile force of the DVT.
