Aims of Research

My research focuses on several disciplines, including the development of skin-like electronics, machine learning algorithms, stretchable transistor circuits, fabrication techniques for soft materials, and the synthesis of various nanomaterials.

The ultimate goal is to seamlessly integrate the developed hardware with artificial intelligence. This integration will pave the way for advanced electronics like intelligent sensors and neuromorphic devices.

Machine Intelligence

Leveraging Machine Intelligence, we can decode signals from a variety of functional devices and uncover concealed patterns. This innovative approach marks a significant milestone in applications related to health monitoring, motion tracking, and soft robotics, providing a transformative perspective in these fields.
This research includes Meta-learning with soft wearable sensors for few-shot learning of multi-task daily electronics for virtual keyboard-less typing, object /gesture recognition (Nature Electronics, 2023), and  Soft skin-sensor combined with machine learning for gesture prediction with single sensor. (Nature Communications, 2020)

Skin-like Devices

Development of highly stretchable and flexible electronics designed to withstand extreme conditions. The scope of this research includes creating highly stretchable conductors, transparent electrodes, and multifunctional sensors.

This research includes Highly Stretchable Multi-dimensional  Strain Sensor (Nano Letters, 2015), and Stretchable Skin-like Sensors. (Nature Electronics, 2023)

Human-Machine Interface

Human-Machine Interface facilitates the measurement of diverse stimuli including pressure, strain, and electrophysiological signals. These devices are designed to be flexible and stretchable, thereby enhancing user comfort and compliance.

This research includes Wearable 3D touch sensor with laser fabricated transparent electrode detecting 3D information with single sensor. (Nature Communications, 2019), and Wireless electronics in ultra-thin PCB circuits measuring human-physiology and gestures. (Adv Func Mat, 2021).

Manufacturing method for skin-electronics

Rapid laser processing allows us to achieve various micro/nano patterns on flexible or stretchable substrates, eliminating the need for high-temperature or vacuum environments. These patterns serve as the basis for a range of electronic components, including conductive electrodes, insulating materials, and transistors.
