Abstract: A soft haptic device and a local control method are disclosed. The soft haptic device includes a soft actuator. The soft actuator includes an electroactive polymer film, a patterned electrode, and a dielectric liquid injected between the electroactive polymer film and the patterned electrode. The soft actuator generates a reconfigurable shape such that a form of an output shape and a number of outputtable shapes are changed depending on the number of electrodes constituting the patterned electrode, a shape of the electrodes, and an arrangement of the electrodes.

Abstract: This disclosure provides a method and apparatus for multicolor unmixing through iterative mutual information minimization in a simultaneous channel update structure. In this disclosure, a plurality of images may be obtained with respect to a plurality of fluorophores labeled on different biomolecules, respectively. Images of the fluorophores may be unmixed from the obtained images, respectively, while simultaneously minimizing mutual information shared between the obtained images based on all permutation combinations of the obtained images. According to the present disclosure, signals having three or more fluorophores whose emission spectra are overlapped in one spectral range can be more accurately unmixed.
