Energy Harvesting, the technology of energy generation from the environment or from the mechanical deformation of ceramics – as in this particular case of piezoelectric ceramics - has diverse fields of application.

Udo Zipfel, Head of Sales and Purchasing at Johnson Matthey Piezoproducts, emphasizes that, for example, wireless data transfer no longer requires an external power supply or batteries.
This kind of energy generation by means of piezoelectric ceramics is employed in the field of energy-autonomous wireless systems. Possible applications are wireless switches using no batteries or external power supplies for control tasks or for radio transmitters of tyre pressure sensors. In the field of automation technology, too, there are applications in which sensors are powered battery-free by using piezoelectric ceramics. 
"A mechanical deformation of the piezoelectric ceramics or the piezoelectric ceramic component is used to produce energy", as Zipfel explains the role of the piezoelectric ceramics. "In the simplest case, a piezoceramic disc is deformed by pressure or tensile stress. In other cases, bending or torsion elements may be deformed." The electrical energy is won by tapping off the load arising at the electrodes due to the deformation of the piezoelectric ceramics. In order to achieve a maximum generation of energy, care must be taken during mechanical deformation of the piezoceramic that the mechanical stresses arising in each case all show the same direction. The generated electric charges will then also have the same polarity.  
Zipfel illustrates the principle: "In the simplest case, think of it like this: By pressing a light switch the piezoelectric ceramic is deformed. The electrical energy thus generated is sufficient to operate an electronic unit that transmits a radio signal to a receiver - for example, to a lamp - causing it to light up ".
Once again at this year's SENSOR + TEST fair in Nuremberg, one of the world's leading trade fairs for sensor technology, measurement and testing technology, the Redwitz company presented its product range: piezoceramic actuators and sensors that are used, for example, in textile machines, automobiles, medical devices and industrial products.
But the focus was on products for sensors and energy harvesting applications using piezo technology - which at the same time was the central theme of its trade fair presentation.
"We are very pleased with the outcome of this year's 'SENSOR + TEST' fair", as Udo Zipfel, Head of Sales and Purchasing of Piezoproducts, emphasizes.  "The fair is an ideal platform for us to showcase our products to an international audience. Moreover it is held in Nuremberg, right on our doorstep. The professional exchange at the highest international level is of great interest in terms of know-how and globalization for most of the trade visitors." 
Today, at an appropriate distance in time to the fair in mid-May, Zipfel is able to draw a positive balance for the Upper Franconian company with regards to the "SENSOR + TEST" fair. We received many international visitors. Good and promising contacts were made which we will continue to expand in the coming months. Also, we again had good opportunities of refreshing our existing contacts."  Johnson Matthey Piezoproducts not only considers the sales aspects but also the purchase aspects of the fair. "We are not only represented as an exhibitor of our products at the SENSOR + TEST fair, we are also always interested to find potential suppliers of new and innovative components that we can use for our products. We regard the exhibition as a success in this respect, too."

Successful Presentation at the electronica Trade Fair 2012

Successful Presentation at the electronica Trade Fair 2012

Many international visitors at the Johnson Matthey booth

Redwitz, December 2012 – „The electronica fair in Munich this year was once again a success for Johnson Matthey Piezoproducts, " as Udo Zipfel, Piezoproducts Sales and Purchasing Director, is pleased to comment. „We were able to greet many international visitors with interesting ideas for products and have already arranged subsequent meetings with a lot of our guests“. Electronica, the world's leading trade fair for the electronics industry, serves Johnson Matthey as an ideal platform for the presentation of the company’s own products but also as a point of contact for present and future customers and suppliers to Johnson Matthey.
The 25th electronica fair took place this year from 13th to 16 th November. 2,669 exhibitors presented their products in Munich to more than 72,000 visitors from 49 countries. For many years Johnson Matthey has been regularly present at the fair exhibiting piezoceramic actuators and sensors, but also systems where piezoceramic actuators are combined with electronic and mechanical components which are used in various applications worldwide.
The Piezoproducts Business Unit presented a selection of Piezoceramics which are used as actuators or in sensor applications. The main focus was on the broad spectrum of bending actuators used in different applications such as in textile machines, in cars, in medical engineering or in industry. "Since we offer customized solutions, both for the ceramic parts themselves, and in the form of complex modules with mechatronic components, we are able to address the needs of our customers in an even more individualized and comprehensive manner'' as Udo Zipfel explains. “This is also reflected in the long-term partnership with our customers.''
The fair is one of the most important for Johnson Matthey Piezoproducts. The next electronica fair will be in Munich again from 11th to 14th November 2014.
