Kendi Enerjisini Üretebilen Klavye Tasarımı
Üretimdeki gelişmeler düşük güçlerde çalışan devre tasarımları ve ağ tekniklerini ortaya çıkarmıştır. Küçülen katı hal elektronik cihaz denetimleri insanları daha savunmasız yapmıştır.Bu nedenle elektronik cihazların güç gereksinimleri azalmıştır.Azalan güç talebiyle enerji sistemleri, pillere alternatif sistemlerin kullanılma olasılığı ile birlikte alternatif aygıtları ortaya çıkarmıştır.Enerji ile çalışan aygıtlarda ortamdaki hareket enerjisinin yakalanması ve bu enerjinin kullanılabilir elektrik enerjisine dönüştürülmesi için Piezoelektrik malzemeler kullanılması mümkündür.Bu çalışmada farklı klavyelere uygulanabilecek çeşitli boy ve uzunluklarda piezo elektrik malzemeler ve yaylar kullanılmıştır.Uygulanan kuvvete bağlı olarak piezo lektrik üzerinde oluşan gerilmelerle elektrik enerjisi üretilmiştir.
Anahtar Kelimeler:

Keyboard Design Producing its Own Energy
The development in production has posed circuit patterns operating in low energy and network techniques. Therefore the energy requirements for electronic devices have decreased. With decreased demand in energy systems, besides the probable use of devices alternative to batteries, new devices have been emerged. Piezoelectric materials have been used in power operated devices in order to capture the kinetic energy in the media and to convert it into usable electrical energy. In this work piezo electric material applicable to various keyboards with various with and length dimensions and spring configurations were used. Depending on the applied force, electrical energy was generated by the stress induced on the piezo electric device.
