The first one includes biosensors, which use electrical responses that occur through the diffusion of reaction products to the transducers. A high-applied potential and fluctuant concentrations of the product, which can result in interferences, decrease in electrical currents and limits of detection, ...
Guidewires and catheter pressure transducers are based on the principle of electro-mechanical pressure transducers [9–11]. Often, the pressure-sensing device is integrated in a complex catheterization, with multiple functionalities [12]. Commercial products are well established in urology and ...
