A Study on Electrical Properties of Controlled Delamination Material
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Primarily used in aerospace applications, Controlled Delamination Material (CDM) has recently drawn attention to the traditional packaging industry due to its low-cost and electrical easy-open. Sinuate®, a CDM product, consists of two aluminum foils bonded together with a conductive epoxy adhesive. When applying a little electricity on its surface, the material can open easily without violence and release without residue. In this paper, a brief introduction on Sinuate® will be presented at first. And some test results on the electrical properties of the joint opening/detaching process will be shown and analyzed.

Intelligent and Interactive Package Based on RFID and WSN

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- An intelligent and interactive package can interact with people smartly, safely and friendly. It involves many technologies such as electronics, optics, biologic, magnetics and electro-mechanics. By combined with Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN), intelligent and interactive packaging technology has been an emerging and global research topic over the years. In this thesis, a new technology, named Controlled Delamination Material (CDM), is introduced. It was primarily used in aerospace applications in the past and further developed by Stora Enso AB. A CDM product can delaminate easily in a controlled way by the use of electrical current. This concept opens up many interesting application possibilities for the traditional packaging industry. In order to understand the delamination mechanism, some related work on the electrochemical characteristics of the material showed the possibility to facilitate the interactive packaging system design. A paper-based package which is integrated with RFID system and CDM is presented to realize an intelligent and interactive system. It can be opened automatically through a finger touch. The opening action is controlled electrically by RFID system. The test results of the demonstration have proved feasibility of the solution and shown the potential for mass production. Following this solution, an interactive pharmaceutical package for pervasive healthcare is proposed by using EPCglobal Gen2 RFID technology. A Gen2 RFID system significantly increases the efficiency of information exchange, and reduces the medication error rate and the possibility of sale counterfeit drugs. It makes the medication accessible for patient only at the prescribed dose and time, and at the same time, the information for the action of taking medication will be delivered to the doctor as well. Such interactive pharmaceutical package not only gives unprecedented high patient compliance, but also improves the communication between patients and healthcare staffs. By integrating WSN with various bio-chemical sensors, in addition to temperature and moisture sensors, more kinds of information can be involved in the intelligent and interactive packaging communication system. It enhances the functionalities of the package such as rotecting the integrity and effectiveness of product, providing safety information details, and being child resistance, senior friendliness

Konferensbidrag (refereegranskat)abstract
- Interactive packaging is an emerging research area in recent years. It brings people convenient and smart lives, reduces consumption of traditional packaging materials and direct or indirect labor costs as well. Being integrated in interactive packaging, Radio Frequency Identification (RFID) technology becomes one of the most proactive development enablers. In this paper, an interactive and intelligent packaging solution integrating passive RFID system and Controlled Delamination Material (CDM) is given at first. Package opening action is electrically controlled by the RFID system. CDM is primarily used in aerospace applications in the past and the conductor/adhesive joint can be easily opened by applying a little electric power on to the material. Some related works will be shown about the electrochemical characteristics of CDM in order to facilitate the system design. A demonstration system was developed and the test results have proved feasibility of the solution and shown the potential of low cost for mass production. Based on this solution, an interactive medication package for pervasive healthcare is further developed, using EPCglobal Gen2 RFID technology. It will make the medication being accessible for patient only at the prescribed dose and time, and medication taking information will be delivered as well. Such medication package will not only give unprecedented high patient compliance, but also improve the communication between patients and healthcare staffs.

A Novel Acceleration Data Compression Scheme for Wireless Sensor Network Application in Fresh Food Tracking System

Konferensbidrag (refereegranskat)abstract
- An enhanced dual-layer wide area wireless sensor network (WSN) system was developed and applied in fresh food tracking application. The sensor nodes of WSN provide a set of useful measurements about the environmental conditions during the fresh food transportation. Since the 3-axis acceleration data in such application account for more than 99% out of all collected source data, we propose a novel acceleration data compression scheme for this specific application, to overcome the resource and cost limitation imposed on embedded sensing nodes and wireless communication links in WSN. According to general fresh food transport behavior pattern, the acceleration data can be extracted into three components (D waveform, A waveform and P waveform). Each component could be compressed separately according to its distinct characteristic and then packetized as an encoded frame. In this paper we examine the experimental acceleration dataset from a field test (fresh melon fruit transport from Brazil to Sweden in 20 days) as a test case. Experimental results show that a high compression ratio (around 10:1) with the acceptable distortion could be achieved, confirming the effectiveness of the compression scheme proposed in this work.

Konferensbidrag (refereegranskat)abstract
- A mobile and wide area deployable wireless sensor system, including hardware and software, is developed to enhance the mobility, deployment and capability of wireless sensors for networked services. Due to the dual-layer dual-directional wireless communication capability of a novel WAN-SAN coherent architecture and the removal of fix-installed gateway, all sensor nodes are remotely controllable and seamlessly integrated to internet services. Hardware modules are optimized for ultra low power and compact size. Abstract and extendable application interface is developed, based on SMS and TCP/UDP protocol, to be integrated easily into existing service systems. Hierarchical CPS-LPS Adaptive Localization, is supported based on CPS, wireless cellular ID, RFID, IR-UWB and inertial prediction. Specific data compression technique is adopted for high density data source. Finally, Fresh Food Tracking service is presented as an application example, including some field test data.
