Microcontroller based low-cost device for quartz crystal microbalance

Abstract

Development of simple and low cost chemical/biological sensors forms an important research area for interdisciplinary sciences. Piezoelectricity based Quartz Crystal Microbalance QCM systems may be readily utilized in testing newly developed sensor materials. In this work, construction of a simple, hand held, computerized QCM apparatus is proposed. Most of the sensor applications usually encountered in freshman laboratories can be performed with this system and the proposed electronic circuit can be assembled by the students themselves.

Microcontroller based low-cost device for quartz crystal microbalance

Abstract

Basit ve düşük maliyetli kimyasal/biyolojik algılayıcıların geliştirilmesi disiplinler arası bilimler için önemli bir araştırma alanı oluşturmaktadır. Piezoelektrik temelli Kuartz Kristal Mikrobalans QCM sistemleri yeni geliştirilen algılayıcı malzemelerinin testinde kolaylıkla kullanılabilmektedir. Bu çalışmada, yapımı kolay, elde taşınabilen bir bilgisayarlı QCM aygıtının tertibi önerilmiştir. Genellikle birinci sınıf öğrenci laboratuvarlarında karşılaşılan algılayıcı uygulamalarının büyük bölümü bu sistemle gerçekleştirilebilir ve önerilen elektronik devre öğrencilerin kendileri tarafından monte edilebilir.
