“…All chemical sensors described in this sub-section are of the chemoreceptor type. Electric tongues have been achieved through directly copying the functionality of the human tongue by creating microchips with arrays of electrode recognition sites or "taste buds" [13,34] with some systems employing pattern recognition algorithms [5,35]. Directly mimicking the human taste bud is a piezoelectric quartz crystal with a molecularly imprinted polymer coating, one that has an enhanced "memory effect," which is inherently stable, long-lasting, can be washed and has high reproducibility [36].…”

Abstract:Sensors are an integral part of many engineered products and systems. Biological inspiration has the potential to improve current sensor designs as well as inspire innovative ones. This paper presents the design of an innovative, biologically-inspired chemical sensor that performs "up-front" processing through mechanical means. Inspiration from the physiology (function) of the guard cell coupled with the morphology (form) and physiology of tropomyosin resulted in two concept variants for the chemical sensor. Applications of the sensor design include environmental monitoring of harmful gases, and a non-invasive approach to detect illnesses including diabetes, liver disease, and cancer on the breath.

“…They rely on the concept of global selectivity, according to which the measurements yield a ''finger print'' of the liquid or vapor under study. Several kinds of sensing elements and detection methods have been studied for e-noses and mainly e-tongues [45,51,[57][58][59][60][61][62], which allow applicability in fields as food [57,[62][63][64][65][66], wines [67], water [68] and pharmaceutical analysis [66]. The importance of the e-tongues and e-noses to biosensing stems from the possible extension through the incorporation of sensing units capable of molecular recognition [69][70][71][72].…”

An overview is provided of the various methods for analyzing biosensing data, with emphasis on information visualization approaches such as multidimensional projection techniques. Emphasis is placed on the importance of data analysis methods, with a description of traditional techniques, including the advantages and limitations of linear and non-linear methods to generate layouts that emphasize similarity/dissimilarity relationships among data instances. Particularly important are recent methods that allow processing high-dimensional data, thus taking full advantage of the capabilities of modern equipment. In this area, now referred to as e-science, the choice of appropriate data analysis methods is crucial to enhance the sensitivity and selectivity of sensors and biosensors. Two types of systems deserving attention in this context are electronic noses and electronic tongues, which are made of sensor arrays whose electrical or electrochemical responses are combined to provide “finger print” information for aromas and tastes. Examples will also be given of unprecedented detection of tropical diseases, made possible with the use of multidimensional projection techniques. Furthermore, ways of using these techniques along with other information visualization methods to optimize biosensors will be discussed.

“…There are several reviews on the subject of e-nose and e-tongue technology, including reviews on e-noses (Di Giacinto et al, 2010;Wilson and Baietto, 2009), biomimetic/biotechnology e-nose and/or e-tongue sensing systems (Rudnitskaya and Legin, 2008;Ghasemi-Varnamkhasti et al, 2010)], applications for e-noses and e-tongues (Scampicchio et al, 2008), neural networks for e-noses (Lu et al, 2000), pattern recognition techniques (Berrueta et al, 2007); meat quality assessment by e-nose (GhasemiVarnamkhasti et al, 2009) and computational methods for analysis of e-nose data (Jurs et al, 2000). This review will concentrate on the recent literature on applications of e-noses and etongues in the food industry.…”
