Keywords:
Thisbook describes a robust, low-cost electrochemical sensing system that is able todetect hormones and phthalates - the most ubiquitous endocrine disruptorcompounds - in beverages and is sufficiently flexible to be readily coupledwith any existing chemical or biochemical sensing system. A novel type of silicon substrate-based smart interdigitaltransducer, developed usingMEMS semiconductor fabrication technology, is employed in conjunction with electrochemical impedance spectroscopy to allow real-time detection andanalysis. Furthermore, thepresented interdigital capacitive sensor design offers a sufficient penetrationdepth of the fringing electric field to permit bulk sample testing. The authorsaddress all aspects of the development of the system and fully explain its benefits.The book will be of wide interest to engineers, scientists, and researchersworking in the fields of physical electrochemistry and biochemistry at theundergraduate, postgraduate, and research lev

els. It will also be highly relevantfor practitioners and researchers involved in the development of electromagneticsensors.
