Bu LabIt is a fingertip-size motor for the application of barcode readersdesigned by recent actuator technology in Bu laboratory.Thistiny motor is composed by a permanent magnet, a coil, a mirror and a support silicone polymer, driven by external current,and the motor resonantly vibrates at 50Hz as a result of elasticity of the silicone polymer. The motor weighs 3 grams and withstands more than 100,000G mechanical shock. Using 3D computer simulations,we study the dynamic performance as well as the structural analysis of the motor and investigate the best motor design for each different application.Actuatortechnologystudiedinmylaboratorycanbeappliedtovariousotherfieldsincludingthefieldofopticalscanning,Forexample,wemaybeabletodeveloparobotthatcaninternallyexploreahumanbodyusingsoftpolymerswithgoodtissueaffinitytohumanbodyandsealingthissoftmotorintoacapsule.Itisnolongeradreamthatthistypeofmedicalrobotcaninspectdiseasesandevencarryoutsurgicaloperationsinsideahumanbody.Dr. Bu YinggangHe is an assistant professor from 2012 and wasan engineer for optical scanning device at Optoelectronics Co., Ltd. from 2009-2012.
