Selective heating of a microparticle surface had been observed to cause its autonomous movement in fluid medium due self-generated temperature gradients. In this work, we theoretically investigate the response such an auto-thermophoretic particle near planar wall which is held isothermal. We derive exact solution energy equation and employ Reynolds reciprocal theorem obtain translational rotati...

simple structure, high accuracy, rapid response, and large working range (Peng et al. 2011, 2012, 2016; Uchino 2008). Recently, linear piezoelectric motors with long motion range, high resolution, and compact size are highly desired in many applications, such as positioning of optical elements, alignment of measurement samples, and manipulation of biological specimens. In various fields, dual s...

The automated shape optimization of an electrostatic micromotor with radial field is tackled. Two objectives in mutual contrast i.e. static torque and torque ripple, depending on two design variables, are considered. An innovative procedure for vector optimization which aims at obtaining as many optimal solutions as possible, is presented. To this end, a non-dominated sorting genetic algorithm ...
