Aiming for application development
of "piezo electric wire sensor"

Piezo wire sensor

"Piezo electric wire sensor" that detects the movement and vibration of the target

We have developed a "piezo electric wire sensor" that detects movement and vibration, and are currently commercializing it. A "piezo electric wire sensor" is made by wrapping a piezo film (piezoelectric element) around a conducting wire and forming a micro coaxial cable with a diameter of 0.5 mm. Since it is thin and flexible, it can be transformed into any shape, and it is self-powered and generates sensor signals by itself.

Detect aging

Detecting aging of industrial machines by vibration measurement

Compared to conventional acceleration sensors, the "piezo electric wire sensor" can clearly measure and judge the rotational vibration of the object to be measured (*). This makes it possible to accurately determine when to replace blades in industrial machinery and to prevent defects. In addition, the ultra-thin wire shape makes it easy to install even later, and it is expected to be applied in various industrial fields, such as for motion monitoring of robot arms and construction machinery. (*Demonstration uses effective value judgment of sensor waveform)

Application development

Application development of cloth-like tactile sensors

By weaving ultra-thin sensor wires into cloth, it is possible to obtain a cloth-like tactile sensor that is flexible and has good air permeability, and that can be processed by cutting, sewing, and dyeing. Since it is non-invasive and has no metal allergy, it is expected to be applied to the medical and nursing care fields. By placing this sensor under a bed sheet, it is expected to be used for alarming when a baby or person in need of care gets out of bed, and for monitoring movements such as apnea and rolling over.

Future business development

Future business development

Vibration sensors for processing machines and robots, for which inquiries are increasing, will be commercialized within this year. We will also develop IOT devices that can be connected to these products, and further develop collaboration with AI diagnostic systems. We are also aiming to commercialize a "watching sensor" based on a cloth-like tactile sensor by the second half of next year. We are planning to raise funds to promote research and development of these products and enhance sales activities.
