Thanks to JJHitt for this rough translation of the Japanese page:
There is an ability to convert mechanical energy and electrical energy
alternately in the piezo-electric device. Various applications such as
ultrasonic dispatching and vibrating sensor and signal filter have been born
making use of this character.
At our company it started advancing the development which removes electrical
energy from the piezo-electric device which still is unreclaimed field in
these application fields.
The light-emitting diode which lights up mechanical energy making use of the
piezoelectric バイモルフ element and that
energy which change in electrical energy (LED) molding as one unit, the part
luminous stick where new concept shines personally (LES) it developed the
fact that this time it introduces.

Like below there is a feature which is superior in this element, development
of future various applied applications is expected.

* General purpose as a part increases by the fact that it unifies, promotion
and future cost decrease of standardization become possible.
* As the whole with the mold material vulnerability of the ceramics is
supplied by the fact that impregnation it does, it improved anti-
environmental efficiency.
* Converting collision energy of the self to electrical energy, because it
radiates, カオティック of the motion
body it made the production of the light which is adjusted to the movement
possible.


*Reference information
External size 2 we plan those of size of type.
Long size: Length 46 mm× width 10 mm× thicknesses 3 5 mm
Short size: Length 30 mm× width 8 mm× thicknesses 3 5 mm<<<

Anyone know more?

Thanks
