    Wearable bioelectronic systems are one of the most important tools for human health and motion monitoring. However, there is still a great challenge to fabricate high-performance flexible devices with a conformal integration of the human body and there is no single device that can collect and correlate data simultaneously from chemical and mechanical signals of the human body. We recently developed a new method to build aerogel-based strain and sweat sensors (aB-SSS) that can effectively extract real-time information by combining involuntary human motion and chemical signals due to their gradient functionalities. these sensors provide good mechanical integrity and allow high-density power generation during subtle human motion, Allowing sweat monitoring by measuring pH, ion concentration, perspiration rate,etc.

    Screen engineered field effect Cu2O based solar cells
    (Institute of Electrical and Electronics Engineers (IEEE), 2020) Department of Electrical and Electronics Engineering; Ergen, Onur; Çelik, Ecem; Ünal, Ahmet Hamdi; Erdolu, Mert Yusuf; Faculty Member; PhD Student; Undergraduate Student; Department of Electrical and Electronics Engineering; Koç University Surface Science and Technology Center (KUYTAM) / Koç Üniversitesi Yüzey Teknolojileri Araştırmaları Merkezi (KUYTAM); College of Engineering; 272106; N/A; N/A; N/A
    We demonstrate cuprous oxide (Cu2O) based screen engineered field effect solar cells with a record breaking efficiency, exceeding 3.486%, for Cu2O based p-n homojunction. In this architecture, CuO nanowire interphase is successfully employed in the Cu2O fabrication by effectively serving as a simultaneous ohmic current collector. These screen engineered field effect photovoltaic principles are essential in developing promising photovoltaics architectures for hard-to-dope materials that, in principle, enable extremely low-cost, high efficiency solar cells.
