Skin-Interfaced Hybrid Electronics for Clinical-Grade Wearables
Prof John A. ROGERS, Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering, Biomedical Engineering, Mechanical Engineering, Electrical Engineering and Computer Science, Chemistry and Neurological Surgery, Northwestern University
Over the last decade, a convergence of new concepts in materials science, mechanical engineering, electrical engineering and advanced manufacturing has led to the emergence of diverse, novel classes of ‘biocompatible’ electronic and microfluidic systems with skin-like physical properties. These devices gently laminate onto the skin in a physically imperceptible fashion to produce continuous, clinical-grade measurements of biophysical and biochemical signatures of health status. This talk describes the key ideas and presents some of the most advanced devices, including (1) wireless electronic sensors for maternal, fetal, neonatal and pediatric health, with examples of scaled, active deployments in the most advanced hospitals in the US and across clinics in multiple countries in Africa and (2) microfluidic platforms that can capture, manipulate and perform biomarker analysis on microliter volumes of sweat, with applications in precise hydration management, screening for cystic fibrosis and nutritional status assessment.

He received SM degrees in physics and chemistry in 1992 and a PhD degree in physical chemistry in 1995 from MIT. From 1995 to 1997, Rogers was a Junior Fellow in the Harvard University Society of Fellows. He joined Bell Laboratories as a Member of Technical Staff in the Condensed Matter Physics Research Department in 1997 and served as Director of this department from the end of 2000 to 2002.

In the Fall of 2016, he joined Northwestern University as the Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering, Biomedical Engineering and Medicine, with affiliate appointments in Mechanical Engineering, Electrical and Computer Engineering and Chemistry, where he is also Director of the recently endowed Querrey-Simpson Institute for Bioelectronics. His research has been recognized by many awards, including a MacArthur Fellowship (2009), the Lemelson-MIT Prize (2011), the Smithsonian Award for American Ingenuity in the Physical Sciences (2013), the Benjamin Franklin Medal from the Franklin Institute (2019) and a Guggenheim Fellowship (2021).

Industry 4.0, a.k.a. the cyber-physical systems, point to a future where humans will be more like robots (i.e., digital, computational, connected to the internet, etc.) whereas robots will be more like humans (i.e., soft, human-mimetic actuation and sensation, artificial intelligence, etc.). This talk will introduce my research on the mechanics, materials, bio-integration and functionality of soft electronics based on inorganic but high-performance functional materials such as metals, silicon, carbon nanotubes (CNT), and graphene. In particular, epidermal electronics, a.k.a. electronic tattoos (e-tattoos), represent a class of noninvasive stretchable circuits, sensors, and stimulators that are ultrathin, ultrasoft and skin-conformable. My group has invented a dry and freeform “cut-solder-paste” method for the rapid prototyping of multimodal, wireless, or very large area e-tattoos that are also high-performance and long-term wearable. The e-tattoos can be applied for physiological sensing for healthcare as well as human body digitization for human-robot interaction. While e-tattoos are to be worn by humans, e-skins are to be worn by robots. Recently, we have engineered an e-skin based on barely electrically conductive porous nanocomposite laminated with an ultrathin insulating layer. The hybrid piezoresistive and piezo-capacitive responses of this novel e-skin have enabled unprecedented pressure sensitivity at large pressures. It, therefore could be applied for sensing very subtle surface pulse waves from the temporal artery even under the pressure of a VR headset. A stretchable version of it could be much more sensitive to out-of-plane pressure than in-plane strain and hence can be mounted on an inflatable manipulator to perform diverse tasks. A perspective on future opportunities and challenges in this field will be offered at the end of the webinar.

Bioelectronics for Wireless Therapy and Diagnostics
Assistant Professor John HO, iHealthtech, National University of Singapore
Recent advances enable electrical and optical control of biological processes with exquisite spatiotemporal resolution. Implantable bioelectronic devices could translate these sophisticated capabilities into more precise therapies, but the long-term operation of such devices in the body remains a significant challenge. In this talk, we describe wireless technologies for powering bioelectronic devices deep within the body and achieving miniaturization at the scale of a single millimetre. We demonstrate applications of these technologies for potential treatments such as cardiac stimulation, optogenetics, and phototherapy.

Numerical Simulation in Wearable and Flexible Electronics
Dr Zhuangjian LIU, Institute of High Performance Computing, A*STAR Research Entities
The one of next-generation technology for electronics is wearable and flexible electronics systems. This type of electronics system should be sustained large deformations geometrically without causing failure in the materials and microstructures, in which it is constructed. There are wide applications of wearable and flexible electronics systems such as communicative packaging, flexible sensors, medical devices and soft robotics, which required flexibility and conformability at the system level.
Numerical modelling and simulation, which is based on computational mechanics studies, are powerful tools for understanding the performance and aided design of these systems. The modelling and simulation can be used to find the stress and strain in the devices under the usage conditions and to provide and establish design criteria. It is important to design this type of device without defect and failure during usage. Furthermore, the numerical simulations are useful to optimize mechanics and electronic performance through coupled multi-physical modelling and materials selection in the design of electronic circuits with maximum stretchability. The numerical modelling and simulations are used to investigate the mechanics and electronic performance of materials and structural systems for this type of electronic device, which has excellent bendability and stretchability. The high flexibility makes them very useful and advantageous for wearable devices with large strains. It is a potential way to make high-performance devices with significant-high stress or strain without failure during different applications.

Body Area Network – Connecting and Powering Things Together Around the Human Body
Assoc Prof Jerald YOO, National University of Singapore
Body Area Network (BAN) is an attractive means for continuous and pervasive health monitoring, providing connectivity and power to the sensors around the human body. As the human body absorbs the majority of RF energy around the GHz band, existing RF radio may not be ideal for communications between and on-body sensors, and this is also true for wireless powering. To solve these issues, this talk presents the Body Coupled Communication (BCC)-based BAN. BCC BAN utilizes the human body itself as a communication medium, which has orders of magnitude less pathloss when compared to RF in the BAN environment. We will look into the channel characteristics followed by design considerations and transceiver implementation examples. Lastly, we will discuss the Body-Coupled Power Transfer and Energy Harvesting – using the same mechanism as BCC, we can power up the wearables throughout the body. We will conclude the talk with future aspects of BAN lying ahead.
