Hanyang University Unveils Advanced Tunable Electronic Skin Technology

Seoul, South Korea – Researchers at Hanyang University ERICA (https://www.hanyang.ac.kr/web/eng/research-excellence-e?p_p_id=kr_ac_hanyang_bbs_web_portlet_BbsPortlet&p_p_lifecycle=0&_kr_ac_hanyang_bbs_web_portlet_BbsPortlet_action=view_message&_kr_ac_hanyang_bbs_web_portlet_BbsPortlet_messageId=115801) in South Korea have developed a novel electronic skin technology capable of detecting both touch and proximity. The innovation is designed to enhance human-robot and human-prosthetic interactions through electrically tunable sensitivity.

The study, published in *Nano Energy*, introduces a vertically integrated dual-gated tribotronic transistor. This architecture enables the electrical tuning of sensor sensitivity while supporting high-density, large-area integration, addressing a significant challenge in the development of advanced electronic skin systems.

Hanyang University: Key Capabilities and Applications

The newly developed electronic skin demonstrates several key functionalities:

Multi-Modal Sensing: The technology can detect touch, pressure, and proximity, offering a comprehensive sensory input for various applications.
Tunable Sensitivity: A core feature of the design is its electrically tunable sensitivity, allowing the sensor to adapt to different environmental requirements and interaction types.
High-Density Integration: The compact vertical design facilitates the creation of high-density sensor arrays, crucial for intricate robotic and prosthetic interfaces.
Demonstrated Performance: Researchers successfully demonstrated finger-touch sensing using a 10 × 10 array. The system was also able to detect objects up to 500 micrometers away, indicating fine spatial resolution.
Durability: The electronic skin maintained stable performance over 1,000 operational cycles, suggesting reliability for long-term use.

This advancement is poised to impact several fields, including robotics, where it could lead to more responsive and safer interactions; prosthetics, by providing users with a more natural sense of touch; and wearables and healthcare systems, enabling new forms of physiological monitoring and human-machine interfaces. The continuous development in this sector is a significant part of the latest tech appliance news (https://technosports.co.in/) and ongoing industry developments.
