“…The EIB is a versatile platform that can be modified to measure different food hazards through replacement of biological recognition elements. EIBs can be manufactured using consumer-grade inkjet printers (Rosati et al, 2019a , b ). The EIB for a bacteriophage produced using an inkjet printer showed better sensitivity than a traditional method for bacteriophage detection (Rosati et al, 2019a ).…”

“…EIBs appear to be a sensitive and cost-effective means of food hazard detection suitable for mass production. With advances in mobile phone technology, there have been a number of studies concerned with integration of EIBs into smartphones (Huang et al, 2018 ; Rosati et al, 2019b ). In the near future, EIBs are expected to be implemented throughout the food supply chain as for inline and real-time monitoring of food hazards.…”

Electrochemical impedimetric biosensors (EIBs) have a simple structure and can be used to rapidly and sensitively detect and measure hazards in food. EIBs detect and measure target molecules by transducing biochemical reactions on their surface to electrical signal outputs responding to a sinusoidal electrical signal input. Due to their structural simplicity and analytical sensitivity, EIBs are regarded as the most potent method of food hazard monitoring that can be implemented in the food supply chain. This paper discusses the theoretical background, structure, and construction of EIB and its applications in food safety.

“…In this paper, we exploited a low-cost sensor printing system based on silver nanoparticle (AgNP) inks [32][33][34] and a commercial inkjet printer to obtain an 8-channel surface EMG matrix. In a previous study, the reliability of inkjet-printed electrodes for a single EMG sensor was investigated and compared to Ag/AgCl standard electrodes.…”

“…Design and fabrication. The design and fabrication of the devices were performed following the method and protocols previously defined and optimized for the production of inkjet printed impedance-based sensors [32][33][34] and SEMG electrodes 10 . The only variation was the production of the insulating layer with patterned adhesive sheets, detailed below.…”

The use of surface electromyography (sEMG) is rapidly spreading, from robotic prostheses and, muscle computer interfaces, to rehabilitation devices controlled by residual muscular activities. In this context, sEMG-based gesture recognition plays an enabling role to control prosthetics and devices in real-life settings. The aim of our work was to develop a low-cost, print-and-play platform to acquire and analyse sEMG signals that can be arranged in a fully customized way, depending on the application and the users’ needs. We produced 8-channel sEMG matrices to measure muscular activity of the forearm using innovative nanoparticle-based inks to print the sensors embedded into each matrix using a commercial inkjet printer. Then, we acquired the multi-channel sEMG data from 12 participants, while they were repeatedly performing 12 standard finger movements (6 extension and 6 flexion). Our results showed that inkjet printing-based sEMG signals ensured significant similarity values across repetitions in every participant, a large enough difference between movements (dissimilarity index above 0.2), and an overall classification accuracy of 93%-95% for flexion and extension, respectively.

“…Research studies have been carried out on inkjet deposition of functional coatings in ceramics [33][34][35], electronics/conductive structures [36][37][38], energy storage devices [39,40], sensors [41][42][43], and biological membranes [44][45][46]. Drop-on-Demand based printers have been used for the fabrication of functional layers in SOFC manufacturing [24,[47][48][49][50].…”
