Problems solved by technology

However, the piezoelectric sensing label in this case is attached to the sealing part of the goods, that is, above or below the goods. Therefore, if the goods are damaged on other ends, there may be monitoring loopholes
Although the overall monitoring can be realized by attaching the piezoelectric sensing labels to the six ends of the goods, the piezoelectric sensing labels need to be attached to each end of the goods one by one. When the piezoelectric sensing labels are packaged on the bottom of the goods, then Operational inconvenience may be caused by overweight cargo or items that cannot be dumped or turned over

Embodiment Construction

[0011] First, if figure 1 As shown, the piezoelectric sensor 1 is ring-shaped, and a conductive layer 12 is deposited or coated on a stretchable flexible substrate 11 as an electrode layer for transmitting charges. Preferably, the flexible substrate 11 is A flexible printed circuit board (Flexible Printed Circuit, FPC), welded with a row of pins, on the conductive layer 12, a corresponding box 2 (not shown in the figure) is attached to the conductive layer 12 through anisotropic conductive film (ACF) ) of the number of sensing elements 13 on the end face 22, and the upper and lower end faces of the piezoelectric sensor 1 are respectively packaged with polyethylene terephthalate (PET) by OCA optical glue to form the piezoelectric sensor 1 .

[0012] Secondly, if 1~ figure 2 As shown, when the goods are loaded into the box body 2 and sealed with tape, the bottom of the box body 2 can be placed above the piezoelectric sensor 1, and then, the two ends of the piezoelectric senso...

Abstract

The invention discloses a stretchable piezoelectric sensor for real-time logistics monitoring. According to the stretchable piezoelectric sensor, a conducting layer is formed on a stretchable soft substrate, sensing components whose number corresponds to the number of end surface of a casing are attached to the conducting layer, so that when the piezoelectric sensor is arranged in the bottom of acasing, the two ends of the piezoelectric sensor can be stretched to sleeve the diagonal of the casing, the sensing components are arranged in the different end surfaces of the casing, and comprehensive monitoring is realized.

Description

technical field [0001] The invention relates to a piezoelectric sensor, especially a piezoelectric sensor capable of stretching a box bundled with goods to sense whether the goods are dropped, pressed or unpacked during transportation. Background technique [0002] At present, there are many patents related to the technology of monitoring goods. For example, Patent No. I289795 in Taiwan, China discloses electronic seals using electronic seals to prevent goods from being dropped or lost. Tracking system, however, the electronic seal cannot know the condition of the goods or help to clarify the cause and responsibility of the goods damaged. In addition, although China Taiwan Patent No. M483492 discloses an impact indicator with a permanent color change and a logistics monitoring and management system with the impact indicator when the goods are attached to the impact indicator to cause the goods to be impacted or vibrated, however, The system needs to take pictures and upload...
