#### Contribution to solving social problems through MOEMS technology that enables equipment miniaturization

Toshihisa Atsumi
Manager, Hamamatsu Photonics K.K
Abstract
MOEMS (Micro Opto Electro Mechanical Systems) technology, which adds optical functions to MEMS, is effective for miniaturization and mass production of spectrometers and scanning mirrors. Devices that were previously used in laboratories and hospital diagnostic rooms have been miniaturized and made into portable devices, etc. They are now being used in places close to our daily lives. On the other hand, many developed countries are facing the challenges of declining working-age populations, global warming, and plastic waste. In this talk, I will present how MOEMS technology can contribute to these social issues with specific examples.

#### Soft Materials for Bioresorbable Medical Devices

Yeonsik Choi
Assistant Professor, Yonsei University
Abstract
Modern integrated circuit technology has an impressive ability to maintain stable operation with exceptional reliability, often without undergoing any physical or chemical changes. However, a new class of electronic materials offers the opposite outcome – transient devices that can dissolve, disintegrate, or disappear at specified times or rates. Water-soluble transient electronics present intriguing possibilities for bioresorbable medical implants, which can be tailored to dissolve based on an individual’s body chemistry. In my presentation, I will introduce fundamental concepts in chemistry, materials science, and assembly processes related to the development of bioresorbable medical devices. As an illustrative example, I will discuss wireless electronic stimulators designed to treat temporary bradycardia.

#### Towards brain-wide neural electrical recording

Xiaojie Duan
Associate Professor, Department of Biomedical Engineering, College of Future technology, Peking University
Abstract
Brain-wide neural activity recording with high spatiotemporal resolution is important for unraveling the intricate orchestration of neural processes that underpin cognitive functions. Here we present our progress in developing high channel-count, high-density neural probes with lengths in the range of 10-90 mm, covering the brain size of rodents and primates. With the thousand simultaneously recorded channels, unprecedented probe length, excellent mechanical stability, and flexible recording site distribution, these probes enable a brain-wide neuronal recording in both rodents and non-human primates. In terms of large-area electrocorticography (ECoG) recording, we developed a shape-changing electrode array which can be implanted in a minimally-invasive manner into the brain of both rodents and canines. The brain-wide neural recording with high spatiotemporal resolution by these neural probes and electrode array enable a wide range of new experimental paradigms for fundamental and translational neuroscience studies.

#### Material and Scaling Aspects for Biosensors and Cell-Device Interfacing with Micro- and Nanoelectronic Devices

Sven Ingebrandt
Professor, Director of the Institute of Materials in Electrical Engineering 1 in the Faculty of Electrical Engineering and Information Technology, RWTH Aachen University
Abstract
Engineered materials and their special properties in the nanoscale regime play a pivotal role for biosensor and bioelectronic applications. Four examples will be demonstrated: First, materials and devices for in vitro monitoring of cells and tissue. There, classical materials such as metals and semiconductors and conductive polymers in organic electrochemically gated transistors will be compared. Second, we will show examples for in vitro monitoring of cells and for detection of ions in sweat. Third, ultrathin 2D materials are highly beneficial for biosensing platforms to detect small biomolecules. Finally, for long-term neuro stimulation purposes, conductive polymers and 2D materials might not be the best choice of material due to stability issues and the generation of reactive oxide species. There classical electrode materials such as iridium oxide are beneficial. In conclusion, different classes of materials are utilized in biomedical monitoring devices, but there is no “one fit all” solution.

#### From Human Mimicry to Robotic Mastery: How Sensor-Driven Telerobotics Paves the Way for AI Imitation of Complex Tasks

Nilupul Nuwan Senevirathna
Technical Engineer at TsukArm Robotics, TsukArm Robotics / Shibaura Institute of Technology
Abstract
Bridging the gap between human dexterity and robotic capability is a key challenge for a smart society. In this talk we will introduces a framework that transitions from human mimicry to robotic mastery. Our approach leverages an intuitive sensor-driven telerobotics system, founded on MEMS-based wearable inertial sensors, to capture the nuances of human motion. This high-fidelity demonstration data then trains an AI imitation model, enabling the robot to autonomously replicate and adapt to complex tasks. By directly translating human skill into machine intelligence, this methodology dramatically accelerates robot programming, unlocking new applications in dexterous manufacturing and human-robot collaboration.

#### Progress in Next-Generation Power Electronics Driven by SiC Power Semiconductors

Yasunori Tanaka
Director, Advanced Power Electronics Research Center, National Institute of Advanced Industrial Science and Technology (AIST)
Abstract
Since the majority of losses in power converters originate from power semiconductor devices, reducing device losses is essential to improving overall efficiency. Traditional power semiconductor devices based on silicon (Si) are approaching their theoretical performance limits due to their own material properties. Consequently, new approaches are being sought, including the adoption of wide bandgap (WBG) semiconductors. Among them, silicon carbide (SiC) stands out due to its high critical electric field, excellent thermal conductivity, compatibility with existing Si processing technologies, and scalability in wafer manufacturing. In this presentation, the historical development of next-generation power electronics technologies based on SiC, along with the current status of SiC power device adoption and recent technological advances, will be introduced.

#### Development of MBS-LAB: an Automated Bio-Experiment System for Microgravity Conditions in Low Earth Orbit using Our Semiconductor-Based Microscopic Observation Device

Masano Nakayama
IDDK Co., Ltd.
Abstract
Numerous bio-experiments have been conducted on the International Space Station (ISS). As private sector involvement in space grows, the importance of space-based bio-experiments continues to increase. However, the upcoming retirement of the ISS, high costs, and limited opportunities remain significant challenges. To address these issues, we are developing a low-cost bio-experiment platform using low Earth orbit satellites. Specifically, we have developed MBS-LAB, a fully automated bio-experiment system for microgravity environments, integrated with a semiconductor-based Micro Imaging Device (MID). Furthermore, MBS-LAB employs a proprietary scripting system called “RECIPE” for device operation, allowing experimenters to implement experimental protocols on the system without the need to directly edit control programs. In this talk, I will introduce the details of both MID and MBS-LAB.

#### Towards the Future of Fisheries

Akihiro Takemura
Professor, University of the Ryukyus
Abstract
Towards the Future of Fisheries: Sustainable Synergy between Land-based Aquaculture and Agriculture Future issues in food production from the perspective of the fisheries sector are food shortages due to population growth, the sustainability of energy supply, the negative impacts of food loss and waste, and the management difficulties in fisheries caused by a shortage of persons bearing responsibility. The creation of a new industry that transcends the traditional boundaries between agriculture and fisheries may be a way to solve these issues. The goal is to realize a circular society where young people take the lead in cultivating and providing food. Under three key targets – (1) establishing a foundation for efficient food circulation, (2) developing core technologies for energy circulation, and (3) advancing technologies for high-level utilization of information – we will pursue the development of technologies such as the recirculating aquaculture systems, efficient electricity management, and agricultural production including aquaponics. These technologies will be thoroughly integrated through smart systems and packaged as a new agriculture-fisheries integrated industry for global deployment.
