Triboelectric Energy: A Micropillar‐Assisted Versatile Strategy for Highly Sensitive and Efficient Triboelectric Energy Generation under In‐Plane Stimuli (Adv. Mater. 2/2020)

Changhyun Pang, Sung Beom Cho, and Sungwoo Chun report a novel and general method for efficient triboelectric energy generation, by assembling artificial micropillars on typical triboelectric nanogenerator devices. The hairy‐structured devices can efficiently harvest electrical energy from in‐plane stimuli such as contact rubbing pressure or noncontact airflow, which works even for extremely small mechanical variations (<0.2 Pa) efficiently.

Spray Coating Technologies: Conductive Hierarchical Hairy Fibers for Highly Sensitive, Stretchable, and Water‐Resistant Multimodal Gesture‐Distinguishable Sensor, VR Applications (Adv. Funct. Mater. 50/2019)

Changhyun Pang, and co‐workers develop conductive hierarchical hairy fibers for a highly sensitive, stretchable, and water‐resistant multimodal gesture‐distinguishable sensor. With multimodal resistance and three‐dimensional microhairy structures on the conductive fiber, the sensor detects three distinct stimuli from the human body. Due to high sensitivity and distinguishability, the presented device is anticipated to be useful for virtual reality applications.
