CMOS Capacitive Sensors for Lab-on-Chip Applications
A Multidisciplinary Approach
Article
In this paper, we review the recent advances of CMOS-based capacitive sensors for Lab-on-chip (LoC) applications. LoC design is a multidisciplinary approach of adapting classical biochemical assays to a miniat...

Chapter
The capacitive sensing electrodes on the top of a CMOS chip serve as an interface between the microelectronic readout system and the biological/chemical analyte. These electrodes are directly exposed to the an...
Chapter
The capacitive measurements of deposable sensing electrodes are conventionally performed using Electrochemical Impedance Spectroscopy (EIS) [331, 332]. As shown in Fig. 6.1a, such a measurement device is conne...
Chapter
The design criteria of capacitive interface circuits for LoC applications differs from conventional MEMS based applications such as acceleration, vibration or pressure [238]. As already mentioned in Chapter 2,...
Chapter
Laboratory-on-Chip (LoC) is a multidisciplinary approach used for the miniaturization, integration and automation of biological assays or procedures in analytical chemistry [1-3]. Biology and chemistry are exp...
Chapter
In Chapter 2, we discussed the design and implementation of sensing electrodes atop CMOS chip. The sensing electrodes are incorporated with biological substances for sensing purposes as shown in Fig. 3.1.
Chapter
A CMOS-based LoC system would require efficient microfluidic packaging to protect the circuitry from the biological and chemical analytes, as well as the external environment. Microfluidic packaging is also cr...
