The drug delivery and targeting method of gold tourmaline composite atoms generated by optical tweezers in a micro-optical device system is proposed.Gold atoms can be trapped and mixed into the tourmaline content,from which the composite gold tourmaline atoms can be formed using the optical tweezers,which can be delivered close to the desired target cells for cells healing and enhancing applications.In simulation,the optical tweezers are formed by whispering gallery(leaky)modes of light can be generated within a modified add-drop filter,which is known as a Panda ring resonator.It is a nonlinear micro optical device,from which the optical probes called optical tweezers can be generated and used for atom trapping,removing and transportation.In this paper,the optical tweezers are designed for gold tourmaline composite atom trapping,in which the trapped gold tourmaline atoms can be deposited(removed)on(from)the surface for cosmetics and cells enhancing treatment usages.The advantage of the proposed scheme is that the applied(removed)atoms to(from)the surface treatments by the designed trapping and storage device,where the device controlled switching is the key function.In application,the composite trapped gold-tourmaline atoms can be stored with the storage device.In addition,the removal trapped gold-tourmaline atoms can be removed from the treatment surface,from which the used gold atoms can be possible extracted and reused.The cells enhancing and healing applications using the tourmaline properties such as magnetic and far infrared are also plausible. 展开更多

A PANDA ring resonator circuit has been applied to the measurement of muscle actions,measuring signals created by facial muscle contractions.A system,which is called the Optical Muscle Sensing System,was developed which uses sensors to measure the mechanism of facial muscle contractions and the strength of contraction and degrees of perturbation of the facial muscles that are used directly for each facial gesture.The signal data was obtained from the simulation of the facial gestures and this data was applied in the classification of the facial gesture signals of each particular gesture.Facial gestures include blinking,smiling,grimacing and various other contortions of the face which may imply emotions and are part of normal human communication.Understanding of these mechanisms will be useful and applicable to facial rehabilitation services. 展开更多
