This paper presents a shock detection device for packages in the supply chain. The primary purpose is to identify package damage during storage, delivery, and handling. Additionally, products are likely to be damaged if dropped from a certain height, which sometimes does not appear on the package. By continuously measuring package vibrations and detecting shocks in the supply chain, consumers can gain an insight into the state of the product upon delivery. This paper presents the Smart Sticker implementation for ultra-low-power shock detection in the supply chain. The overall energy consumption must be kept as low as possible while continuously sensing the presence of shock to ensure that the Smart Sticker's battery lasts as long as possible. The Smart Sticker functions in three modes to meet the established constraints: low-power, active, and data transfer mode. While detecting the shock, the low-power mode uses the least amount of energy needed. If the shock exceeds the threshold, the Smart Sticker enters active mode, stores the detected g force value in memory, and then switches back to low-power mode. Finally, employing Near Field Communication (NFC) and energy harvesting, the data transfer mode allows the consumer to read the recorded data. The results show that the Smart Sticker for shock detection performs according to set requirements and successfully monitors and detects shock for packages in the supply chain.
本文提出了一种用于供应链中包装的冲击检测装置。其主要目的是在储存、运输和处理过程中识别包装损坏。此外，如果产品从一定高度掉落，即使包装上没有显示，产品也很可能会损坏。通过连续测量包装的振动并检测供应链中的冲击，消费者可以在产品交付时深入了解产品的状态。本文提出了用于供应链中超低功耗冲击检测的智能贴纸实现方案。为了确保智能贴纸的电池尽可能长时间地持续使用，必须将整体能耗保持在尽可能低的水平，同时持续感知冲击的存在。智能贴纸有三种模式来满足既定的约束条件：低功耗模式、活动模式和数据传输模式。在检测冲击时，低功耗模式使用所需的最小能量。如果冲击超过阈值，智能贴纸将进入活动模式，将检测到的重力值存储在内存中，然后切换回低功耗模式。最后，采用近场通信（NFC）和能量收集，数据传输模式允许消费者读取记录的数据。结果表明，用于冲击检测的智能贴纸符合设定要求，并成功地监测和检测供应链中包装的冲击。
