Skin-inspired bioelectronics
Skin is the body’s largest organ. It is responsible for the transduction of a vast amount of information. This conformable, stretchable, self-healable and biodegradable material simultaneously collects signals from external stimuli that translate into information such as pressure, pain, and temperature. The development of electronic materials, inspired by the complexity of this organ, is a tremendous, unrealized materials challenge. However, the advent of organic-based electronic materials may offer a potential solution to this long-standing problem. Over the past decade, we have developed materials design concepts to add skin-like functions to organic electronic materials without compromising their electronic properties. An important discovery was nano-confined polymer semiconductors and conductors. This finding addressed the long-standing challenge of conformational disorder-limited charge transport with polymer electronic materials. It enabled us to introduce various skin-like functions while simultaneously increasing polymer electronic material charge transport ability. The above fundamental understanding further allowed us to develop direct photo-patterning methods and fabrication processes for high-density large-scale soft stretchable integrated circuits. In addition, we developed various soft sensors for continuous measurements, including pressure, strain, shear, temperature, electrophysiological and neurotransmitter sensors. The above sensors and integrated circuits are the foundations for soft bioelectronics and enable a broad range of new tools for medical devices, robotics and wearable electronics.

Nanogenerators for implantable medical devices and self-powered biosensors
A self-powered system can sustainably operate without an external power supply for sensing, detection, data processing and transmission. Nanogenerators (NG) were first developed for self-powered systems based on the piezoelectric effect and triboelectrification effect for converting tiny mechanical energy into electricity, which have applications in the Internet of things, environmental/infrastructural monitoring, medical science, environmental science and security. NGs have three major application fields: micro/nano-power sources, self-powered sensors and blue energy. We will present the applications of the NGs for harvesting body motion energy that will be used for medical science and bioengineering.

Intrinsically-soft conductors for conformal tissue-device interfacing
Recent advances in flexible and stretchable electronics have attracted significant attention due to their potential applications in personalised bio-integrated healthcare devices. The mechanical mismatch between conventional rigid electronic devices and soft human tissues often causes various issues, such as a low signal-to-noise ratio of biosensors, inflammations on the tissue interfacing with the bioelectronics, skin irritations in the case of long-term wearing of the device and ineffective electrical stimulations in feedback therapies. Ultra-flexible and stretchable bioelectronic devices have a low system modulus and intrinsic softness and, thereby, have the potential to solve these issues. Nanomaterials and their composites with the elastomeric matrix are particularly promising material candidates for realising this soft bioelectronics concept. This talk presents the unique strategies in synthesising nanomaterials, processing as stretchable functional nanocomposites, seamless integration into soft bioelectronics, and their wearable and/or implantable device applications. These efforts have combined recent nanomaterials and soft electronics breakthroughs and are expected to address unmet clinical challenges.

Plenty of room under the skin: A wearable’s perspective
The use of wearable electronic devices that can acquire vital signs from the human body noninvasively and continuously is a significant trend for healthcare. The combination of materials design and advanced microfabrication techniques enables the integration of various components and devices onto a wearable platform, resulting in functional systems with minimal limitations on the human body. Physiological signals from deep tissues are particularly valuable as they have a stronger and faster correlation with the internal events within the body compared to signals obtained from the surface of the skin. In this presentation, I will demonstrate a soft ultrasonic technology that can noninvasively and continuously acquire dynamic information about deep tissues and central organs. I will also showcase examples of this technology’s use in recording blood pressure and flow waveforms in central vessels, monitoring cardiac chamber activities, and measuring core body temperatures. The soft ultrasonic technology presented represents a platform with vast potential for applications in consumer electronics, defense medicine, and clinical practices.

Ubiquitous Bioelectronics: Personalizing Medicine for Everyone
In this talk, I will discuss how bioelectronics can be positioned as ubiquitous biomarker data harvesters to enable molecular diagnostics at the point-of-person for personalized medicine. Aligned with this vision, I will present the central theme of my research program: developing new classes of bioelectronics that autonomously measure biomarker molecules in various biofluids to provide deep insight into our body’s dynamic chemistry and facilitate timely actionable feedback. These bioelectronics can be either integrated with users’ daily experience and surroundings, for example in a mobile format, for frequent monitoring and decentralized testing—or they can be directly integrated with body, in wearable and implantable formats, for continuous monitoring. I will provide example technologies developed by my lab that can increase our capacity for harvesting biomarker data by orders of magnitude for real-time intervention and generation of high quality, large multidimensional data sets. I will specifically present:

·      A low-cost, yet powerful, digital microfluidic technology, namely ferrobotics, that miniaturizes and automates complex assays within a palm-sized circuit-board-based platform and produces lab-grade test results (e.g., reducing NAAT test/person cost by 300-fold, Science Robotics 2020 & Nature 2022).

·      A series of bioanalytical smartwatches, microneedles, and touch-based interfaces that non/minimally-invasively measure circulating biomarker molecules such as metabolites, hormones, pharmaceuticals, in real-time (PNAS 2020 & 2022, Nature Comm. 2020, Science Advances 2020 & 2022) along with associated clinical data on stress monitoring and precision dosing.

·      A library of soft, stretchable, tissue-interfacing bioelectronics that feature clinically favorable interfacial materials (including brittle noble metals) and deliver high biosensing/stimulation performance without being affected by strain and corrosion (Science 2022).

I will conclude by discussing how through convergent and multidisciplinary efforts (including engineering, medicine, and data science), we can harness such technologies for point-of-person health monitoring and realize personalized health at the population scale.

Intelligent skin electronics for healthcare monitoring and XR
Soft bio-integrated electronics have attracted great attentions due to the advantages of soft, lightweight, ultrathin architecture, and stretchable/bendable, thus has the potential to apply in various areas, especially in the field of biomedical engineering. By engineering the classes of materials processing and devices integration, the mechanical properties of the flexible electronics can well match the soft biological tissues to enable measuring bio signals and monitoring human body health.

In this report, we will present materials, device structures, power delivery strategies and communication schemes as the basis for novel soft bio-integrated electronics. For instance, we will discuss a wireless, battery-free platform of electronic systems and haptic interfaces capable of softly laminating onto the skin to communicate information via spatio-temporally programmable patterns of localized mechanical vibrations. The resulting technology, which we refer as epidermal VR, creates many opportunities where the skin provides an electronically programmable communication and sensory input channel to the body, as demonstrated through example applications in social media/personal engagement, prosthetic control/feedback and gaming/entertainment. Other demonstrations will include a flexible bio piezoelectric microsystems for tissue pathology biopsies (cancer diagnosis), and skin like patches as sweat sensors for healthcare monitoring and energy harvesting

Providing a clinician’s touch through wearable technologies
The growth of flexible and wearable electronics commensurate with the proliferation of microelectronic devices is enabling high impact applications in healthcare and robotics. However, as such electronic devices increase in number, an increasingly urgent need to create materials and devices that can be part of a circular or self-repairable economy becomes critical. In this talk, I will discuss using organic hybrid materials science and engineering approaches as a way to scale skin-like electronic devices for more sustainable technological and societal impact through self-healing or degradability.

Further, to scale-up to human-like performance, neuromorphic engineering provides an exciting avenue to mimic the high performance of the human nervous systems and sensors. Critically, the energy efficiency of the human neural networks for learning relies on event-driven, temporally encoded action potential streams. In this talk, I will discuss how we can digitize tactile information through inspiration from somatosensory neural science. For example, we have developed an asynchronous protocol for parallel transmission of tactile information in an artificial peripheral nervous system we call ACES: Asynchronously Coded Electronic Skins. The parallel transmission encodes spatial temporal information with very high temporal precision (sub-100ns) even when large numbers > 10,000 sensor nodes are transmitting simultaneously. Such systems can be interfaced with soft sensors or flexible/stretchable electronics to enable more intuitive robotics and healthcare applications.

Wearable elastography via surface mechano-acoustic sensing for continuous monitoring of tissue stiffness
Recent progress in wearable devices provides new opportunities for precise, non-invasive, long-term recording of body mechanics. The soft device incorporating a single MEMS accelerometer captures subtle vibration of the skin with a resolution of 1×10-4 g/√Hz in the frequency range from 0 to 800 Hz. In this study, we introduce an on-body mechano-acoustic sensing technology based on a skin-mounted accelerometer array to assess the mechanical profiles of subdermal tissues in-vivo, similar to seismology. A system-level wearable device construction, optimized for a comfortable skin interface and high precision, incorporates a broadband dual-accelerometer sensor, an audio actuator, and a Bluetooth System-on-Chip and enables a wireless, automated operation. An automated algorithm, leveraging the spectral analysis of surface waves (SASW) methods, computes the depth-sensitive, elastic modulus information of the propagation media from the mechanical dispersion relationship. Comprehensive theoretical and experimental investigation on bi-layer phantom materials and biological tissues, with a storage moduli range of 19–1439 kPa, demonstrates the capability of rapid and robust evaluation of modulus in a depth range of 2–46 mm. The device identifies the softening of porcine tissues with increasing injected water content and the changes of modulus of muscle under different levels of tension. The results are in agreement with the in-parallel Ultrasound Elastography measurements. A quantitative assessment of the stiffness profile of the bicep brachii and rectus femoris muscle during gym exercises demonstrate the device operation in an ambulant environment for a non-invasive and continuous assessment of deep tissue stiffness with a temporal resolution of 0.5 s.

Dr Changsheng WU is an Assistant Professor in the Department of Materials Science and Engineering (MSE) at the National University of Singapore (NUS). He is also a PI in the Institute for Health Innovation and Technology and the N.1 Institute for Health, NUS. He received his PhD in MSE from Georgia Tech and carried out postdoctoral research in the Querrey Simpson Institute for Bioelectronics at Northwestern University.
