“…It is important to note that the transducer sensitivity improvement from using the negative capacitance interface not only can be applied to detect structural damage in engineering structures but also can be extended to other fields of research that monitor variations in mechanical quantities by means of corresponding variations in the electrical impedance of transducers. Other fields of research that may employ the results presented here are biomedicine and dentistry with applications such as biomedical diagnostics [18], [19] and dental implant monitoring [20].…”

Sensitivity Enhancement of Piezoelectric Transducers for Impedance-Based Damage Detection via a Negative Capacitance Interface

Piezoelectric transducers are used in many applications due to electromechanical coupling, which allows mechanical and electrical quantities to be related. This principle is used in the development of structural damage detection techniques such as electromechanical impedance (EMI) commonly used in structural health monitoring (SHM), where structural health is monitored by measuring and analyzing the electrical impedance of a transducer. As a piezoelectric transducer is a primarily capacitive device, its reactance becomes small at high frequencies, reducing sensitivity to structural damage and increasing the excitation current required from the measuring system. Therefore, this paper proposes the use of a negative capacitance (NC) interface with the transducer to improve sensitivity to structural damage and reduce the excitation current. The improvement obtained with the NC interface is theoretically analyzed using an electromechanical model and experimentally validated with tests on an aluminum structure. The results conclusively indicate a significant improvement in the sensitivity to structural damage and a reduction in excitation current, which are critical for detecting incipient damage and developing onboard monitoring systems where the output current drive is usually low.

“…Recently, Jasim et al. (2019) reported a microfluidic impedance biosensor for rapid and simultaneous detection of different Salmonella serogroups in poultry products. As illustrated in Figure 6, the device consists of three microchannels, and each one involves a focus region to concentrate samples and a sensing region for bacterial cells detection.…”

“…Salmonella is a species of rod‐shaped Gram‐negative bacteria belonging to the family of Enterobacteriaceae (Ansari, Yazdian‐Robati, Shahdordizadeh, Wang, & Ghazvini, 2017; Silva, Magalhães, Freire, & Delerue‐Matos, 2018). It contains two main species, Salmonella enterica and Salmonella bongori with more than 2,500 serotypes, and all of these serotypes can cause disease in humans (World Health Organization [WHO], 2018) People may get infected with Salmonella through the consumption of contaminated food with some symptoms such as diarrhea, fever, stomach cramps, nausea, vomiting, and headache (Jasim et al., 2019). WHO claims that Salmonella is one of the four major global causes of diarrheal diseases and one of the microorganisms in which some resistant serotypes have emerged (WHO, 2018).…”

Salmonella is one of the main causes of foodborne infectious diseases, posing a serious threat to public health. It can enter the food supply chain at various stages of production, processing, distribution, and marketing. High prevalence of Salmonella necessitates efficient and effective approaches for its identification, detection, and monitoring at an early stage. Because conventional methods based on plate counting and real‐time polymerase chain reaction are time‐consuming and laborious, novel rapid detection methods are urgently needed for in‐field and on‐line applications. Biosensors provide many advantages over conventional laboratory assays in terms of sensitivity, specificity, and accuracy, and show superiority in rapid response and potential portability. They are now recognized as promising alternative tools and one of the most on‐site applicable and end user–accessible methods for rapid detection. In recent years, we have witnessed a flourishing of studies in the development of robust and elaborate biosensors for detection of Salmonella in food. This review aims to provide a comprehensive overview on Salmonella biosensors by highlighting different signal‐transducing mechanisms (optical, electrochemical, piezoelectric, etc.) and critically analyzing its recent trends, particularly in combination with nanomaterials, microfluidics, portable instruments, and smartphones. Furthermore, current challenges are emphasized and future perspectives are discussed.

“…Microfluidic formats of the impedance immunoassays further improve the assay time: 7 CFU mL −1 of multiple Salmonella serogroups were detected in 40 min in poultry and lettuce samples with no interference from E. coli , by bacteria trapping at the interdigitated Ab-modified Au electrodes of a microfluidic biosensor [ 152 ]. In the latter case, live and dead cells were discriminated by their different intensity of the impedance signal.…”

“…Considering the recent reports discussed, electrochemical immunosensors for whole bacterial cells can undoubtedly solve these problems, at low cost and by a constructive detector and instrumental design friendly to minimally trained personnel. Impedimetric, label-free 40 min e-immunoassaying of 7 CFU mL −1 [ 152 ] and 20 min e-ELISA of 50 CFU mL −1 of E. coli [ 98 ] in microfluidic devices are promising examples of the devices for real worlds sample analysis. The same refers to the urease-linked e-ELISA on MBs (12 CFU mL −1 2 h) [ 89 ] and cellulase-linked e-ELISA on MBs (1 CFU mL −1 in 3 h) [ 90 ].…”

Microbiological safety of the human environment and health needs advanced monitoring tools both for the specific detection of bacteria in complex biological matrices, often in the presence of excessive amounts of other bacterial species, and for bacteria quantification at a single cell level. Here, we discuss the existing electrochemical approaches for bacterial analysis that are based on the biospecific recognition of whole bacterial cells. Perspectives of such assays applications as emergency-use biosensors for quick analysis of trace levels of bacteria by minimally trained personnel are argued.
