Pioneered In Piezoelectric Devices For Wearable Devices

Japanese scientists have developed the first application.

The piezoelectric cloth can detect the movement of the wearer.

The breakthrough was co developed by Yoshiro Tajitsu, a Japanese expert who specializes in chemical polymers and textiles, and the Engineering Science Department of Kansai University.

Based on PLA (PLA) fiber and carbon fiber.

It is made up of PLLA (poly L- lactic acid) fibers and carbon fiber electrodes.

Plain weave, twill and satin weave are used for different applications.

Plain weave can induce bending, and satin can be distorted.

It can induce shear and 3D movements, as well as bending and twisting.

Its sensing function is based on the technology of weaving and knitting of the company. It can detect any shift or direction changes of the human body, so that cloth can be applied to drive or inductor to detect complex movements and even 3D actions.

The University of Kansai and the company of Di Di said that the next step is to develop the application of plain weave knitted fabric, as long as it can monitor human activities through clothing.

Piezoelectric effect is a phenomenon that produces charge accumulation in dielectric materials to react with mechanical stress. With the application of voltage, mechanical tensile force will occur in materials, resulting in an opposite effect.

These two effects can be measured so that piezoelectric materials can be effectively applied to sensors and actuators.

Up to now, piezoelectric materials are still limited by the lack of pparency and elasticity, as well as the restrictions on the use of certain hazardous substances in electrical and electronic devices, such as PZT piezoelectric ceramics, such as lead zirconate titanate.

In 2012, Kansai University and di Ren company developed flexible and pparent piezoelectric film through alternation of PPLA and optical isomer PDLA (poly D- lactic acid).

The latest development of piezoelectric materials is the latest research and development results of these technologies.

Jiangsu economic and Information Committee, Yancheng City science and Technology Bureau and Yancheng City economic and Information Committee organized and hosted the appraisal meeting of new products and scientific and technological achievements in Jiangsu Yueda textile group. 5 new products developed by Jiangsu Yueda textile group were appraised by the provincial level.

At the meeting, the R & D personnel introduced the 5 new products' R & D process, the various certification and economic benefits they have obtained.

The members of the appraisal group listened to the technical report of the project development, reviewed the relevant documents and materials, and observed the production site and product samples. After discussion, it was agreed that the products such as "vortex spinning high count yarn", "knitted wool like thermal fabric", "anti ultraviolet far infrared ecological fabric" and "functional nylon 66 fabric" filled the gaps in China, and were the first in China. The technology reached the leading level in China.

The members of this appraisal group are Gao Weidong, vice president of Jiangnan University, Professor Gu Tian Hong, senior engineer of Jiangsu Textile Industry Association, Professor Zhang Keqin of Soochow University, Bai Guohua, senior engineer of Jiangsu textile engineering society, Liang Huie, Dean of textile and garment Institute of Jiangnan University, Yao Xingchuan, Professor of Song Xiaobang, Dean of Textile Research Institute, Song Xiaobang, Professor Song Xiaobang.
