It consists of three yarns made of environmentally friendly piezoelectric, conducting and insulating fibers.　The fiber bundles are wrapped around a wound core that is alternately and spirally intersected, woven and woven in a regular spiral pattern. Furthermore, sufficient electromagnetic shielding is achieved by braiding and overlapping two pairs of bundles composed of conductive fibers. In other words, the structure simulates the shielding structure of a coaxial cable, achieving low noise and high sensitivity. In addition, the piezoelectric fiber is optically active polymer and therefore not pyroelectricity. In other words, it is resistant to temperature changes in the surrounding environment.

Decorative knots tied with piezoelectric braided cord produce unparalleled functionality.
Piezoelectric braided cord generates electrical signals in response to the magnitude of movement. For example, large body movements generate large voltages. At this moment, the pulse wave signal in response to small pulsating movements is buried by the large signal resulting from large body movements and becomes undetectable.

In such cases, it is usually necessary to prepare a PC with complex analysis software or a device with many circuits to separate the response signal from the signal caused by pulsation and the signal caused by body motion.

A system using piezoelectric braided cord solves this problem. This is because piezoelectric braided cord senses only the piezoelectric signal of the motion to be measured, depending on the type of knotting. In other words, using decorative knots with piezoelectric braided cord or embroidering piezoelectric braided cord eliminates the need for a PC and numerous circuits. The rare feature of piezoelectric braided cord is not found in any other sensors.
