Message from Prof. Sekine-sensei

Welcome to the Sekine Laboratory Website!

Established in 2023, the Sekine Laboratory is committed to harnessing the unique characteristics of organic materials - lightweight and flexible - to pioneer unprecedented electronic devices.

Our current research focuses on the development of thin-film sensor devices designed for applications such as wearables and implants, enabling integration with humans and robots alike.

These devices, known as "digital skin," replicate and mimic the exceptional functions of human skin, creating high-performance systems.

Through this innovation, we aim to enhance human skin capabilities and empower robots with skin functions that are equivalent to or surpass those of humans. By combining these advancements with cutting-edge AI technologies, we envision building future technologies that enable the automation of tactile and perceptual functions.
