The motor consists of a hollow carbon cylinder and a disc-type coplanar piezoelectric trimorph actuator. The cylinder is glued in the center of the metal disc. The electrodes of the piezoelectric layers of the actuator are divided into the four equal sections. There are four piezoelectric plates bonded to the bottom face of the metal disk for exciting the stator's out-of-plane flexural vibration mode. The shaft is used to amplify the vibration amplitude of the metal disk. The rotor pressed on the conical surface of the shaft can be driven to rotate by the traveling wave induced friction force. The preload between the stator and rotor is applied by one nut screwed to the solid shaft. A prototype of the proposed motor is fabricated and characterized. The vibration amplitude of the stator's metal disk is measured by the PSV laser Doppler vibrometer. The prototype's rotational speed can reach 5000 r/min and the amplitude of the disk can reach 0.3μm when the driven frequency is 33.186 kHz and the driven voltage is 350 Vp-p.","PeriodicalId":243839,"journal":{"name":"2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132075948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerical results show that the torque deformation produces large effect on the electric displacements but little contribution to the electric potential.

Eight sensors were used in the intelligent insoles and they are designed by double-layer PVDF piezoelectric films. The signals of the sensors was sampled and processed by the signal system composed of the preamplifier circuit and the power frequency filter circuit. The output voltage of the single- and double-layer PVDF piezoelectric thin films were tested respectively. The results showed that under the same pressure, the double-layer structure can increase the output signal of the proposed sensors and therefore the precise of the measurement could be improved.

In this research article, a series of PVDF-TrFE/ZnO thin films were prepared by means of spin-coating method. Different parameters of this process such as the speed of spin-coating and temperature of annealing were discussed. In order to investigate the effect of these parameters on the ferroelectric phase of samples, various characterizations such as SEM, FTIR, XRD and DSC were utilized. Results revealed that annealing temperature played a significant role in the crystallinity of those thin films, the transformation of ferroelectric phase and the perfection degree of crystallization. Besides, with in a certain range, the lower speed of spin-coating favors better formation of ferroelectric phase.","PeriodicalId":243839,"journal":{"name":"2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"277 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125850936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stress function based approach is quite different from the traditional plate and shell theories that adopt the displacement functions as initial assumptions, where the stress boundary conditions are prescribed at the surfaces and applied at the free edges so that the stress components satisfy the boundary conditions automatically. The principle of complementary virtual work is adopted to derive the governing equations, resulting in a set of fourth order differential equations that can be further solved by a general eigen value problem. The proposed methodology is computationally quite efficient and accurate compared with the three dimensional finite element method. We believe the proposed approach can be used as an efficient tool for analysis of static stresses in piezoelectric composite structures.","PeriodicalId":243839,"journal":{"name":"2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121748864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
