- In this work cradle to grave life cycle assessment of printed electronics resources have been presented. An attempt has been made to investigate and evaluate the life cycle assessment and environmental impacts of printed electronics resources such as polymer substrate-printed RFID antenna. Life cycle inventory analysis for these resources has been carried out to quantify total systems' inputs and outputs that are relevant to the environmental impacts especially emissions to air, fresh water, industrial soil and sea water. The results show that printed electronics materials are considerably more environment friendly than materials needed for PCB electronics. We have obtained the mass of emissions in each life cycle stages which verify that technology wise printed antenna causes less harmful and hazardous impacts to the environment.

- The present state of the art research in the direction of embedded systems demonstrate that analysis of life-cycle, sustainability and environmental assessment have not been a core focus for researchers. To maximize a researcher's contribution in formulating environmentally friendly products, devising green manufacturing processes and services, there is a strong need to enhance life-cycle awareness and sustainability understandings among embedded systems researchers, so that the next generation of engineers will be able to realize the goal of a sustainable life-cycle. In this work an attempt has been made to investigate and evaluate the life-cycle management and environmental assessment in fabricating processes of the RFID based systems. We have chosen a general life cycle assessment approach which involves the collection and evaluation of quantitative data on the inputs and outputs of materials and energy associated with the RFID based systems. Based on the developed generic models, we have obtained the results in terms of environmental emissions for a production of paper substrate printed RFID antennas. We also make an attempt to raise several sustainability issues and quantify the toxic emissions during the manufacturing process.

Konferensbidrag (refereegranskat)abstract
- This paper presents quantitative analysis of environmental emissions in different life cycle stages such as raw material preparation (RMP) and production processing (PP) of printed circuit board. A general emission model for printed circuit board (PCB) has been developed to analyze the emissions to air, fresh water, sea water and industrial soil. This work also demonstrates the quantities of renewable and non-renewable resources that are required to manufacture PCBs. Based on these generic models, the environmental assessment has been carried out in a production of one million PCBs. We also make an attempt to give an analytic description for evaluating the amount of emissions in each life cycle stages of the printed circuit board.

- This position paper gives an insight for self-aware and adaptivity requirements of the sub-systems embedded in a satellite spacecraft. The most significant and considerable issues of self-aware and adaptive systems that are necessary in present and future on-board satellite spacecraft are illustrated in this paper. An attempt has been made to discuss several embedded sub-systems and space environment scenarios of the spacecraft. As a case study, an adaptive sierpinski based dual band antenna has been devised. The adaptive nature of this antenna provides a foundation of longer and more reliable mission life of a spacecraft. Through this paper it will be shown that adaptive, reconfigurable and reliability issues are the most prominent and potential area of research for outer space communication technology.

- This paper presents cradle to gate life cycle assessment of printed electronics resources. In this work an attempt has been made to investigate and evaluate the life cycle assessment and the environmental impacts of printed electronics resources such as printed RFID antenna. Life cycle inventory analysis for these resources has been carried out to quantify total systems’ inputs and outputs that are relevant to environmental impact especially emissions to air, fresh water. We have also compared printed flexible substrate structure based on polymer substrate with inkjet material deposition to more traditional PCB technology. The chosen approach can be easily relevant to other flexible substrates and materials or device structures.

- On-paper microsupercapacitors (MSCs) are a key energy storage component for disposable electronics that are anticipated to essentially address the increasing global concern of electronic waste. However, nearly none of the present on-paper MSCs combine eco-friendliness with high electrochemical performance (especially the rate capacity). In this work, highly reliable conductive inks based on the ternary composite of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS), graphene quantum dots and graphene are developed for scalable inkjet printing of compact (footprint area ≈ 20 mm2) disposable MSCs on commercial paper substrates. Without any post treatment, the printed patterns attain a sheet resistance as low as 4 Ω ▫−1. The metal-free all-solid-state MSCs exhibit a maximum areal capacitance > 2 mF cm−2 at a high scan rate of 1000 mV s−1, long cycle life (>95% capacitance retention after 10 000 cycles), excellent flexibility, and long service time. Remarkably, the “totally metal-free” MSC arrays are fully inkjet printed on paper substrates and also exhibit high rate performance. The life cycle assessment indicates that these printed devices have much lower eco-toxicity and global warming potential than other on-paper MSCs.

Tidskriftsartikel (refereegranskat)abstract
- This paper presents comparative environment impact evaluation and assessment between inkjet printing technology based Electrocardiography (ECG) Bio-patch and traditional Printed Circuit Board (PCB) based ECG Holters. Due to the complexity of electronic systems and the consistent lack of solid data about a product’s life cycles, a limited comparison has been carried out to qualify the input and output of raw material resources, energy resources used in manufacturing phases and environmental emissions in end-of-life phases. Based on the GaBi’s balance calculation methodology, a case study is described to illustrated the possibility of environmental potential benefits from above mentioned technologies.

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Printed circuit boards have been massively manufactured and wildly used in all kinds of electronic devices during people’s daily life for more than thirty years since the last century. As a highly integrated device mainly consists of silicon base, an etched copper layer and other soldered components, massive production of printed circuit boards are considered to be environmentally unfriendly due to the wet chemical manufacturing mode and lack of recycling ability. On the other hand, the newly invented ink jet printing technology enables cost-effective manufacturing of flexible, thin and disposable electrical devices, which avoid acid etching process and lead to less toxic emissions into the environment. It is important to consider life cycle analysis for quantitative environmental impact evaluation and comparison of both printed circuit boards and printed electronics to enhance the sustainability of a new technology with product design and development. This thesis first reviews the current approaches to conventional and modern printing methods, as well as the state-of-the-art analysis of sustainability and environmental assessment methodologies. In the second part, a typical ink jet printed electronic device is introduced (an active flexible cable for wearable electrocardiogram monitoring). This active cable is designed for the interconnection between bio electrodes and central medical devices for bio signal transmission. As the active cable consists of five different metal transmission traces which are formed by printing conductive ink onto paper substrates, different shielding methods are investigated to ensure high quality bio signal transmission. Specifically, the results prove that passive shielding methods can significantly decrease the cross talk between different transmission traces, enabling the transmitting of bio signals for wearable ECG monitoring. This research also explores environmental issues related to printed electronics. For the full life cycle of printed electronics, we focused not only on quantitative environmental emissions to air, fresh water, sea and industrial soil, but also on resource consumption and impacts analysis. Finally, comparative environmental performance evaluation of traditional cables and ink jet printed active cables are made to examine the environmental impact and sustainability of both technologies, and the results show the strengths and weaknesses of each technology by analysis and assessment.

- This paper presents quantitative environment impact evaluation and assessment of inkjet printed flexible cable on soft substrates for Electrocardiography (ECG) monitoring. The studied printed ECG cable is fabricated by inkjet printing of nanoparticles wire on paper substrate which enables wireless transmission of ECG signals between bio- electric electrodes and central medical device. In order to facilitate the inventory analysis, the environmental impacts evaluation of inkjet printing technology has been carried out by comparing with traditional ECG cables. With the life cycle inventory modeling by using GaBi software, the life cycle assessment (LCA) was conducted to qualify the input and output of raw material resources, energy resources used in manufacturing phases and the impacts to the environment.

- In this paper, we describe two cutting-edge technologies for the emerging wearable healthcare applications: application specific integrated circuit (ASIC) and printed electronics on a flexible paper substrate. The ASIC enables a compact integration of active circuit blocks on a chip. Due to its tiny size, the ASIC makes the wearable unit unobtrusive and maximizes the wearer's comfort. The electrical performance of a paper based inkjet printed flexible cable is also exhibited. Combining the two technologies together, an example of electrocardiogram (ECG) signal recording is presented.
