3D Flexible Integration (heterogenous integration)
Printed Intelligence for Healthcare
Abstract: Next generation healthcare devices will require embedded electronics to be reshaped and restructured. Moreover, there is also growing need for transient electronics that is bioresorbable and biodegradable. To this end, there is need for flexible, bendable and breathable electronics that is also biocompatible. This talk will focus on the need for novel electronics that is free of hard rigid components, and the landscape around it. I will talk about my research in this domain in building a new class of printable materials to put electronics on unconventional substrates and the printing routes. Printed electronics holds great promise for innovation in design, device architecture and added functionality. The talk will highlighted some key projects completed in the area of printed electronics with application in point-of care and healthteach solutions.
Sustainable ICT (Circular economy, e-waste reduction)
Fabrication and Characterization of Nanomaterial-based Sensor Devices by Metal Organic derived Solution Printing Method
Near future, we will get super smart society (Society 5.0) which a lot of data are gotten form our
physical society by IoT technologies with all sensing systems. The big-data in cyber space are optimized
and added additional values through AI and ICT technologies, and feedback actionable information to
us in the physical space. This concept is calling cyber physical systems (CPS). The CPS will solve all
social issues, and develop new economical services and industries through improving productivity.
Sensing technologies such as gas sensor, and etc. are very important of the IoT devices in CPS.
Sensing with tenuous volatile organic compounds (VOC) gas which contain in human exhalation is
important issue for next generation healthcare. In recent years, gas sensors are much attention research
topics to synthesis oxide semiconductor nano-materials through fabrication conventional devices
product process.
In our previous study, MoO3 nanorod arrays growth on the silica substrate with fixed diameters of
10 nm but controllable length of 20 – 600 nm has been successfully synthesized by a simple solution
metal organic decomposition (MOD) method[1]. We can be recently successful controlled the thickness
of deposited seed layer of MoOx nanorod arrays on the substrate[2]. In addition, TiOx some of
nanostructures also growth on the substrate successfully deposited by the MOD method[3].
In this study, we are demonstrating fabrication of some oxide (include MoO3, and TiOx)
nanostructure gas sensor device for VOC gas with a very simple printed coating process, and the VOC
(such as 1PrOH, EtOH, MeOH, IPA and ACE) gas sensing properties are evaluated by the MoOx and
TiOx sensor devices[3,4]
These gas sensors show good response performance with quick response and recovery time, as well
as various selectivity of each VOC gas. The relationship between adsorption/desorption abilities with
morphology of the nano-structures will be discussed in detail on the symposium.

APPLICATIONS OF AI TO FLEXIBLE ELECTRONICS
Exploring 1D and 2D Nanomaterials for Health Monitoring Wearable Devices
We are witnessing a proliferation of wearable devices in all aspects of our lives, and they are having a tremendous impact on personalized medicine. In this talk, we will report on wearable devices for health monitoring. We will present our research on hybrid nanocomposite-based stretchable strain sensors with 1D sensing material wrapped within dragon-skin (DS) polymer to form a sandwich-like structure. The strain sensors include macro channels filled with one-dimensional inorganic materials (MWCNTs or AgNWs) and organic silicone polymer. Such sensors are employed to monitor subtle and large human body movements such as fingers, wrist, artificial knee joint, and respiratory movements. We will also present our research on exploring 2D MoS2 material for strain and field-effect biosensing application. Integration of 2D nanomaterials into electrical devices offers substantial advantages such as high sensitivity and low form factor for wearable biosensing applications.
Human-Robot Collaboration for Manufacturing/Remanufacturing Process
The scarcity of resources, environmental regulations, and the potential profitability of salvaging operations have motivated manufacturers to consider end-of-use product recovery and remanufacturing. However, the US remanufacturing industry is dealing with many challenges, such as the labor-intensive nature of disassembly, small lot sizes, and the unknown quality and condition of incoming products to recycling facilities. Disassembly is an integral part of many remanufacturing operations such as reuse, repair, maintenance, and recycling. Today, disassembly is still a predominantly labor-intensive process that requires direct contact with many elements that are potentially harmful to human health. This project will advance research to explore effective human-robot collaboration (HRC) in the remanufacturing industry to reduce remanufacturing costs and improve operators’ safety while considering the highly complex unstructured nature of remanufacturing. The research will advance the fundamental study of the way humans and robots distribute tasks, cooperate, and interact in a safe and complementary manner. Improving workers’ quality of life, higher volumes of recycling, higher employment rates, less dependency on other countries for certain materials, and increased stock of domestically harvested rare earth elements are among expected benefits.
