Nano Material Properties Engineering Lab
Machine-translated · View original
The lab builds flexible sensors from inorganic nanomaterials and handles everything through to machine learning.

AboutAbout the lab
From nanomaterials to devices and systems.
The Nano Material Properties Engineering Lab aims to realize highly functional, high-performance devices using inorganic nanomaterials.
Beyond making individual devices, the lab studies everything in one integrated effort: materials, devices, process development, and machine learning for data analysis.
Applications are wide-ranging, including wearable health monitoring systems, electronic skin, IoT, plant health monitoring, and VR/AR.
Undergraduate students also get to take part in international conferences and write papers in English, with the aim of training researchers and engineers who feel no barrier with English.
Key terms
- Inorganic nanomaterials
- Materials such as metals and semiconductors made at the extremely small scale of nanometers
- Reservoir computing
- A computing method that converts input signals into complex responses and reads them out, requiring little training effort
- Electronic skin
- Sensors arranged on a flexible film so that it can sense pressure and temperature like human skin

ResearchResearch themes
The lab aims to make highly functional, high-performance devices mainly using inorganic nanomaterials. Rather than stopping at individual devices, it studies everything from materials to devices to process development, and proposes new devices that fuse different fields.
*Illustrative imagePrinted sensor sheets
Focusing on the electrical properties of inorganic nanomaterials, the lab develops methods to coat them onto large-area films to form thin films. This leads to multifunctional flexible sensors that measure human health conditions and building environments.
*Illustrative imageA mechanism for analyzing data instantly
Combining flexible sensors with reservoir computing, the lab aims to build edge systems that analyze data on the spot. By breaking the convention of one sensor = one output, it lowers power consumption and system complexity.
*Illustrative imageWearable health monitoring
The lab integrates sensor sheets that measure multiple vital signs without harming the body with machine learning algorithms that analyze the data instantly. It works with the Faculty of Medicine on validation tests and toward practical use.
*Illustrative imageElectronic skin and whiskers
The lab integrates sensors that detect the information human fingertips feel onto flexible films. By introducing machine learning, it captures even slip and softness, aiming for use in robots that need instant feedback.
