Biosensors and Bioelectronics

Transducers to Biosensors

A Bio transducer is part of the biosensor system recognition and transmission. It consists of two adjacent parts; a layer of biological recognition and a physicochemical transducer, which works together converts chemical signals into electronic or optical signals. Electronic electronics offers more important advantages than physical, chemical and biophysical methods, in terms of high sensitivity and new sensory processes, advanced spatial adjustment, facial integration and regular use of semiconductor processing and label-free, detection real time in place in a non-destructive way. Gravimetric biosensors apply the basic rule of response to weight change. Most gravimetric biosensors use small piezoelectric quartz crystals, either as crystalline crystals (QCM), or as bulk / surface acoustic wave (SAW) devices. Pyroelectric biosensors generate electrical energy due to temperature changes. This difference creates a separation in the object, producing a dipole moment at which the gradient of the temperature is referred to. The result is a net voltage across all equipment.
