“…Simultaneously, the new generation of information technology represented by wearable Internet of Things (W-IoT) [49], blockchain [50] and cloud computing, have generated immense interest for the nascent flexible sensing because it can integrate and connect personnel, processes, data, and equipment enabling the high adaptability [51], high precision, multiple scale, dynamic non-destructive monitoring [49]. Flexible sensing in food monitoring has become increasingly significant in recent years [44,52,54,55], and is rapidly evolving in its application scenarios [44,48,52,53,54,55], and manufacturing methodology [44,53]. The synergy between flexible sensing and developments in material science and microfabrication technology has been instrumental in the success of both fields with innovations in one driving progress and in the other.…”

“…Flexible sensors have intrinsic characteristics including the ability to bend [44,[51][52][53][54][55], fold [51,55], stretch [68,69,70,71], twist [72], and even self-heal [56,73] if damaged. Flexible substrates are the main contributor to the deformation dynamics of the sensors.…”

“…However, the rigidity hinders the capture of analytes and results in poor signal transduction [77], which limits the performance of conventional sensors. Flexible food monitoring sensors, whether attached to the living organisms' surfaces [44,52,55,78] or integrated inside or outside of packaging [58], need to be lightweight, small, and easy to use [67]. Flexible substrates, taking polymers as an example, are intrinsically or molecularly stretchable materials, which use the materials themselves to accommodate strain [79].…”

Monitoring and maintaining food quality, safety, and authenticity are the most important concerns in the food industry. The cutting-edge flexible sensors for food monitoring precisely meet the needs of acquiring information on multiple parameters in small space and more reasonable layout, providing data on mechanical deformations, and conformably attaching to arbitrarily curved surfaces. Flexible sensing materials with a large specific surface area, high carrier mobility and carrier density, dense active sites, outstanding tunability, and processability, such as two-dimensional carbon nanomaterials, conductive polymers, and nanohybrid materials, have further improved the sensitivity, stability, and selectivity of flexible sensors. This article attempts to critically review state-of-the-art developments with respect to materials, fabrication techniques, and sensing mechanisms of devices, as well as the applications of the electrically-transduced flexible sensors. In addition, this review elaborates on the transduction mechanisms of several typical transducers, with a focus on the physics behind, including the modulation of doping level, Schottky barrier, and interfacial layer that typically lead to changes in conductivity, work function, and permittivity. We also highlight the benefits, technical challenges with corresponding solutions of current flexible sensors, and discuss potential strategies to overcome limitations in energy consumption, quantify the trade-offs in maintaining quality and marketability, optimize wireless communication, and explore new sensing patterns.

“…And, flexible sheet devices are expected as reasonable solutions. [7][8][9][10] However, because the living body parts always move, sometimes the sensors come off or slip off from the positions attached at first or the devices are slightly distorted by mechanical stresses. So, it is worried that deviated or incorrect monitoring data are collected.…”

A new stereophonic projection lithography applying a parabolic magic mirror system was proposed. An aperture was also opened at the bottom of lower mirror, and a transparent reticle was placed in place of a reflective object article used in the conventional magic mirror system. Toward the transparent reticle, illumination light was irradiated obliquely upward from the bottom. Thus, images of curved reticle patterns were projected at the aperture center of the upper mirror, and 200 μm line-and-space resist patterns were actually printed on a silicon wafer when a flat reticle was used. On the other hand, it was clarified by tracing light rays in the meridional plane that the resolution depended on the field size, the extent of used mirror parts, and the defocus. It is considered that aimed 50 μm patterns will be printable if the illumination system is improved. The new method is feasible and hopeful.

Food quality monitoring is increasingly important. This paper aims to propose the developed wireless pressure sensor system (WPSS) for fish quality monitoring. WPSS consists of a sensor acquisition module, power supply module, and Bluetooth module. The sensor acquisition module includes a temperature sensor, pressure sensor, and microcontroller unit (MCU). When Bluetooth receives the data collection command from the smartphone, the data of storage temperature and pressure in the food package can be collected by the sensor and transmitted wirelessly to the smartphone through Bluetooth. All data obtained by the system is monitored, stored, processed, and eventually displayed in a smartphone app in real-time to improve temperature, air pressure, and freshness transparency within the food package, ultimately ensuring food quality and safety. The proposed WPSS has potential application in many kinds of food monitoring. It can realize simple and intuitive food quality indications.
