PolyU researchers unveil liquid metal microelectrodes with soft, stretchable and permeable properties to be used for implantable bioelectronic devices

Electronic devices that can be attached to the skin or even implanted in the body will become more and more prevalent in near-future technology. Such “implantable bioelectronics” are envisaged as having a wide range of uses from medical technology to the emerging field of augmented reality, and a research team led by The Hong Kong Polytechnic University (PolyU) has developed a type of microelectrode that is uniquely suited to devices of this kind. A pioneering study entitled “Wafer-patterned, permeable, and stretchable liquid metal microelectrodes for implantable bioelectronics with chronic biocompatibility”, was recently published in Science Advances. Compared with conventional electronics, materials used for wearable or implantable bio-electronic technology require specific properties that are difficult to bring together. They must be stretchable, soft and permeable enough to survive in the human body without causing discomfort or harm to the user. Meanwhile, like everyday household devices, bioelectronics still depend on electrodes that are highly electrically conductive and can be patterned into microscale circuitry. Led by Prof. Zijian ZHENG, Chair Professor of Soft Materials and Devices and Professor of the Department of Applied Biology and Chemical Technology, the interdisciplinary research team comprises members from PolyU’s School of Fashion and Textiles, Department of Biomedical Engineering, Department of Applied Biology and Chemical Technology, Research Institute for Intelligent Wearable Systems (RI-IWEAR) and Research Institute for Smart Energy (RISE), as well as from City University of Hong Kong and the Hong Kong Centre for Cerebro-Cardiovascular Health Engineering. The team have overcome several technical limitations to advance the field of wearable technology and invented a method of producing unprecedentedly soft, stretchable and permeable electrodes for implantable bioelectronics. The key step in the fabrication process is the electrospinning of a fibrous polymer onto silver (Ag) micropatterns, resulting in an array of liquid metal microelectrodes (μLMEs) that can be patterned at ultrahigh density – up to 75,500 electrodes per square centimetre, thousands of times higher than previously achieved – and that have long-term biocompatibility. The μLMEs can be comfortably worn on human skin, while a specific application in animal brain monitoring has also been demonstrated. Previously, biocompatible electronics were fabricated on porous elastomers, but the porosity and roughness of these substrates limit the patterning resolution and hence the electrode density. By depositing electronic circuitry onto fibrous polymer substrates through the technique of photolithography, the team successfully overcame this obstacle, achieving μLMEs with tissue-like softness, high conductance under severe strain and long-term biocompatibility. A liquid metal alloy known as eutectic gallium indium (EGaIn) was used as the conductive component of the μLMEs, as it has a low melting temperature and retains its conductivity under extreme strain, while being soft and highly biocompatible. The fabrication process involves depositing circuitry patterns comprising EGaIn onto an electrospun, a permeable “fibre mat” of the polymer poly (styrene-block-butadiene-block-styrene). This created soft, stretchable electronics that can be comfortably worn and implanted. The concept of a super-elastic fibre mat was first developed by Prof. Zheng’s team in 2021, and is now adopted in the newly developed μLMEs to guarantee a complete photolithographic transfer of the electrode micropatterns from the Ag template, in contrast to the partial transfer achieved when using impermeable substrates. Apart from being soft, liquid-permeable and air-permeable, μLMEs are also highly stretchable, and their electrical resistance increases only slightly after repeated cycles of stretching and release under high strain. When attached to human skin, an electronic patch fabricated from μLMEs leaves only trace or even no residues after being subjected to pressure. This is a promising property for wearable electronics, for which there is expected to be a huge market with applications in physiological monitoring, medical diagnosis and interactive technology. Most notably, the softness and stretchability of the μLMEs also make them ideal for implantation at the neural interface for brain monitoring. The team synthesised an array of μLMEs with a small electrode diameter and high channel density to serve as an electrocorticography signal receiver in a rat brain. With similar mechanical properties to brain tissue, the μLMEs attached closely to the cortical surface and accurately recorded neural signals in vivo. When the sleeping rat sent out discernible brain waves typical of non-REM sleep, the μLME array reliably detected somatosensory evoked potentials in response to electrical stimuli applied to different parts of its body. As Associate Director of RI-IWEAR and Lead Investigator at RISE, Prof. Zheng stated, “Thanks to the combination of photolithography and soft, permeable SBS fibre mats, microelectrodes with unprecedented resolution and biocompatibility are realised. The technological advancement in medical and augmented reality fields can be pushed forward by these μLMEs, which overcome previous technical limitations to the fabrication of bioelectronics.” Receiving funding from the Research Grants Council’s Senior Research Fellow Scheme, PolyU, City University of Hong Kong, the National Natural Science Foundation of China and InnoHK, the research team intends to build on their accomplishments by increasing the patterning resolution of μLMEs. ***END***

Jinjiang is a city renowned for its famous Chinese brands and remarkable advancements in technology, economy, culture and art. As a world-class research university, PolyU will take Jinjiang as a starting point to support its technological innovation and strengthen technical cooperation in the areas of textiles, smart manufacturing, integrated circuits and sustainable technology. The University will also promote the transformation and application of technological achievement, contributing to the “Jinjiang Experience” of innovation and development in Jinjiang, Quanzhou and Fujian. Prof. Jin-Guang Teng stated that it was his first visit to Jinjiang and he had the opportunity to visit numerous enterprises, leaving him impressed by their “high quality and brand creation”, which are prominent features of Jinjiang's economic and social development. With a strength in basic research and innovation entrepreneurship, PolyU is dedicated not only to producing world-class scientific research, but also to making a positive impact on socio-economic development. Jinjiang's solid and robust industrial foundation provides an excellent platform for PolyU and he believes that the University can become a strong driving force in promoting the development of Jinjiang's science and technology industry, leading to mutual benefits. Mr Zhang Wenxian shared his view that education, technology and talent provide foundational and strategic support for building a modern socialist country, and are also crucial for the high-quality development of the private sector economy. He sincerely hopes that through the platform of the Research Institute the University and the City can deepen their collaboration in the integration of government, industry, academia and research. This will promote deep integration of innovation, industrial, financial and talent chains, and co-create a new paradigm of cooperation between Fujian Province and Hong Kong. The Jinjiang Municipal Party Committee and Government are committed to seizing this opportunity to collaborate, concentrate efforts, aggregate resources and integrate policies. They will join hands with PolyU to focus on industry and strive for innovation and for developing the “Jinjiang Experience”, with the PolyU spirit of “To learn and to apply, for the benefit of mankind” shining brightly in Jinjiang’s new era. Apart from the signing and unveiling ceremony, key representatives from the Research Institute introduced research developments and work plans related to textile technology, future food, microelectronics, innovation and technology policy, to local government representatives, research institutions and enterprises. Officials from the Jinjiang Municipal People's Government visited PolyU for the first time after the resumption of normal travel between Hong Kong and the Mainland early this year. Since then, the two parties have maintained close contact and had frequent interactions, reaching consensus and establishing the Research Institute in six months, demonstrating their strong commitment and a high level of efficiency. PolyU hopes to deepen cooperation with local enterprises in Jinjiang through the Research Institute, promote research and help to transform core technologies, in time expanding from Jinjiang to Quanzhou and the entire province. The University also aims to strengthen industry-academia-research collaboration between Fujian and Hong Kong, build a new paradigm of cooperation between Fujian Province and Hong Kong, and cultivate innovative and entrepreneurial talents with advanced technological knowledge and global vision.   ***End***
