Description

Stretchable pressure sensor for real-time monitoring of logistics

The invention relates to a pressure sensor, in particular to a pressure sensor capable of stretching a box bound to a cargo to sense whether the cargo is severely dropped, heavily pressed or unsealed during transportation.

In order to improve the above-mentioned deficiencies, the Republic of China Announcement No. I289795 discloses a radio frequency tag electronic seal which avoids the loss or loss of goods through an electronic seal and a condition tracking system for recognizing the electronic seal using the radio frequency tag, however, the electronic seal Unable to know the condition of the goods or assist in clarifying the cause and responsibility of the damage. In addition, the Republic of China Announcement No. M483492 discloses a flushing indicator that exhibits a permanent color change and a logistics monitoring management system having the impact indicator when the cargo is attached with an impact indicator to cause the cargo to be washed or shaken. The system requires taking photos and uploading actions, which is time consuming and labor intensive. However, the Republic of China Announcement No. I484440 discloses a logistics certification method and a system with proper certification that can avoid the confiscation of unlicensed consular or logistics personnel. However, the system cannot know the status of the goods or assist in clarifying the goods. The cause of the damage and the attribution of responsibility.

In 2015, the inventor applied for and approved the patent of the Republic of China Bulletin No. I557680 "Logistics Monitoring System Using Pressure Sensing Labels", which is a pressure sensing label. Attached to the top or bottom of the cargo, the cargo can be scanned and registered by the label scanning device at the logistics station, and the sensed piezoelectric value is transmitted to the vehicle-mounted device through the pressure-sensing label during the transportation or during the transportation, and then borrowed. The vehicle-mounted device transmits the signal to the cloud management system to instantly monitor the status of the goods and clarify the responsibility for the damage of the goods. However, the pressure-sensing label of this case is attached to the sealing of the cargo, that is, above or below the cargo, so if the cargo is damaged at other end faces, monitoring loopholes may occur. Although the pressure sensing label is attached to the six end faces of the cargo to achieve full monitoring, the pressure sensing label needs to be attached to each end face of the cargo one by one. When the pressure sensing label is packaged at the bottom of the cargo, then It may be inconvenient for work due to excessive weight of the goods or items that cannot be dumped or turned over.

In view of the previously developed pressure-sensing label, the inventors still have the inconvenience of inconvenience, and have developed and improved again, and formed a flexible ring-shaped piezoelectric detector through a flexible substrate, which can be quickly achieved by using a stretching action. The pressure sensor is combined with the purpose of the goods.

In order to achieve the foregoing, the present invention provides a stretchable piezoelectric inductor for real-time monitoring of a flow, the stretchable piezoelectric detector is annular, and the conductive layer is attached with a corresponding box. The sensing component of the number of end faces enables the sensing elements to be respectively located at the respective end faces of the casing when the two ends of the piezoelectric inductor are bound by the stretching action to the opposite corners of the casing.
