“…The three approaches presented in this manuscript all leverage any existing passive RIFD tag and any RFID reader and does not require any specialized sensors or electronics for detection of package condition. Table 1 lists the comparison of the presented approaches with the most relevant and competitive technologies that require specialized sensors, such as impedance sensor [1], piezoelectricsensor [2], and light sensor [3]. This makes these other approaches slightly more bulky and expensive.…”

“…Piezoelectric polyvinylidene fluoride (PVDF) film has the property of generating an electric charge in response to applied mechanical stress. It has been embedded into a tear-off patch type sensor placed on the opening edge of the package [2]. Opening the package leads to the mechanical stress on the film to generate a voltage pulse, which is sensed and converted to a radio frequency signal by a readout circuit module.…”

Cost-Effective Wireless Sensors for Detection of Package Opening and Tampering

et al. 2020

There is a need to develop a simple cost-effective approach for wireless detection of whether package is or was open en route during transportation. Existing approaches rely on electronic devices that need sensors with on-board and continuous power source for sensing and data logging. This paper presents three different battery-free, cost-effective, Radio-Frequency Identification (RFID)-based solutions for the detection of tampering or package opening. The first solution is for real-time opening detection. Opening or closing the package leads to unfolding or folding of the flexible-based antenna, which activates or deactivates the RFID tag. The second solution is for recording and memorizing package opening using a printed switch that shunts the antenna of the RFID tag. Opening causes a permanent disconnection of this switch activating the RFID. This change is irreversible; thus, the sensor memorizes the specific opening event without any additional electronic memory device. The third solution is for all-around package security using an RFID-based thread. Opening the package from any side allows changes in the radiation profile so the package condition can be wirelessly sensed. The approaches have been simulated and validated experimentally.

“…Sarpong (2014), for example, examined the influence of the horse meat scandal on the European market and its effects on discussions of transparency [20]. In terms of technology use, researchers discussed a variety of procedures, including the use of real-time monitoring for cross-company processes [21]. Other articles discussed the introduction of the Internet of Things and analysis methods based on it [22,23].…”

“…Other articles discussed the introduction of the Internet of Things and analysis methods based on it [22,23]. According to this analysis, the introduction of tracking and tracing technologies is an important step towards a uniform information base across a network [20,21,[23][24][25]. Also of high importance in the field of action for transparency is the use of decision-making tools that provide the decision maker with information permitting a more transparent decision-making process [26,27].…”

The literature contains many analyses of measures against food loss. However, there exists no structured analysis of the objective of these measures. This study employs a systematic literature analysis and open expert interviews, combining the perspectives of science and practice. For each analyzed case, we identified the objectives behind the implemented measures. Using qualitative clustering, we categorized the located objectives into fields of action. The identified 13 fields of action provide an overview of the objectives of food loss prevention measures. The results indicate that different levels of importance can be assigned to these fields of action. In particular, the results show the relevance of increased network cooperation and transparency within a company and along the entire value chain. Furthermore, the study indicates that the creation of transparency provides the greatest overall added value in terms of reducing food losses.

Piezoelectric force touch panels are extensively utilized as human-machine interfaces for 3-dimensional touch sensing in internet of things (IoT) applications. However, the unstable force voltage responsivity issue induced by different touch orientations limits the successful use of piezoelectric touch panels. In this article, a piezoelectric touch panel, which is sensitive to both capacitive and force stimulation, is assembled; and a touch orientation classification technique is developed to calibrate the detected force amplitude by training a machine learning model with finger induced capacitive information. Finally, a high stable force voltage responsivity of 87.5% is achieved experimentally.
