The wafer flexure technique was used to characterize the d31 coefficient of a number of sol–gel and radio frequency (rf) sputtered lead zirconate titanate (PZT) thin films with thicknesses between 0.6 and 3 μm. Typical d31 values for well-poled 52/48 sol–gel films were found to be between −50 and −60 pC/N.

Sensors and Actuators A: Physical, 2002
Abstract A design concept for multilayer piezoelectric microactuator using piezoelectric coefficient d 31 was particularly stressed. Accordingly, two kinds of novel piezoelectric multilayer microactuators, called a split-morph and an annular split-morph, have been proposed and discussed for the dual stage actuation systems in high track density ...

Sensors and Actuators A: Physical, 1998
Abstract This paper describes a simple and inexpensive method for evaluating the transverse piezoelectric coefficient ( d 31 ) of piezoelectric thin films. The technique is based upon the flexure of a coated substrate which imparts an ac two-dimensional stress to the piezoelectric film.

AbstractThirty‐four strains of docosahexaenoic acid (DHA)‐producing microorganisms were newly isolated from brackish areas in Japan. These strains showing various compositions of fatty acids. Especially, the fatty acids produced by one of the strains, named D31, had a high DHA content (over 60 % of the total fatty acids) and the simple fatty acid ...

Low frequency PVDF piezoelectric energy harvester with combined d31 and d33 operating modes
The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2013This paper reports the design, test and application of a novel low frequency piezoelectric energy harvester. To achieve high output voltage at low frequency, both d31 and d33 modes of polyvinylidene fluoride (PVDF) are utilized in this device. Output voltage of the device are tested under different frequencies and accelerations.

Zaštita od buke cestovnog prometa na dionici ceste D31 - spoj D31 na D30 i na D408
2010Za dionicu ceste D31 – spoj na D30 i na D408 izrađen je idejni projekt zaštite od buke. Izrađen je 3D modela prostora za navedenu dionicu. Primjenom računalnog programa LIMA koristeći njemačku i francusku metodu proračuna određene su razine buke. Predviđena vrsta zaštite su zidovi za zaštitu od buke za koje je izvršena optimizaciju njihovih visina i ...

Idejni projekt zaštite od buke cestovnog prometa na dionici ceste D31 - spojna cesta na D408
2012U radu je primjenom računalnog programa LimA koristeći njemačku metodu proračuna utvrđena učinkovitost provedene zaštite na dionici ceste D31 (na predmetnoj dionici izvedena je zaštita 2010. godine) te su predložena pobojšanja. Kao i kod postojećeg stanja, prioritetna predviđena mjera zaštite jest izvedba zidova za zaštitu od buke, za koje je izvršena ...
