ABSTRACT

This chapter discusses the application of power delivery in biosensing. It introduces remotely-powered implantable-systems capable to provide real-time biosensing. The core-idea was to develop a so-tiny implant to support insertion by a siring while supporting the detection of several diseases biomarkers at molecular level and be connected to our smart phones by means of a wearable patch. In order to realise the electrochemical biosensors needed to address the detection of diseases biomarkers at molecular level, electrochemical cells have to be fabricated and correctly driven by designing the typical three-electrodes: the working electrode (WE), the Counter, and the Reference ones. The acquisition of the Faradaic current may be performed by a current-to-voltage conversion with a transimpedance amplifier connected at the WE. The current generated at the WE by redox reactions is called Faradaic current. There are several methods to incorporate carbon nanotubes into an electrochemical sensor.
