14^th Euro Biosensors & Bioelectronics Congress

Types of Biosensors

Optical biosensors are those based on the detection of changes on absorption of UV/visible/Infrared light when chemical reactions occur or on the quantity of light emitted by some luminescent process. A piezoelectric sensor works with the properties of piezoelectric effect, which can vary in changing pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. It can be applicable with medical, aerospace and nuclear instrumentation. Piezoelectric sensor acts as a pressure sensor in the touch pads of mobile phones. Gravimetric biosensor varies under piezoelectric biosensor and it uses thin piezoelectric quartz crystals as resonating crystals or as surface acoustic wave devices.
