Abstract:
광 감지 센서는, 제1 인터디지테이티드(interdigitated) 전극; 제2 인터디지테이티드 전극; 및 상기 제1 인터디지테이티드 전극 및 상기 제2 인터디지테이티드 전극 각각과 접촉하는 광전도층을 포함할 수 있다. 상기 광전도층에 입사된 입사광에 의해, 상기 제1 인터디지테이티드 전극과 상기 광전도층의 계면 및 상기 제2 인터디지테이티드 전극과 상기 광전도층의 계면에 표면 플라즈몬 플라리톤(surface plasmon polariton)이 여기될 수 있다. 표면 플라즈몬 폴라리톤에 의하여 광전도층의 광흡수가 특정 파장 대역에서 증폭될 수 있으며, 이를 이용하여 해당 파장 대역에서 광흡수를 나타내는 물질을 민감하게 감지할 수 있다.
Abstract:
An optical detection sensor includes a first interdigitated electrode; a second interdigitated electrode; and an optical conduction layer which is in contact with each of the first and second interdigitated electrodes. Due to incident light inputted into the optical conduction layer, surface plasmon polaritons can be excited on the interface between the first interdigitated electrode and optical conduction layer, and interface between the second interdigitated electrode and optical conduction layer. The optical absorption of the optical conduction layer can be amplified at a specific wavelength range due to the surface plasmon polaritons and a material which shows optical absorption in the corresponding wavelength range can be sensitively detected using the same.

Abstract:
An attenuated total reflection (ATR) type waveguide mode resonance sensor comprises a waveguide layer being in contact with a sample and formed of nanocrystalline diamond (NCD). The incident angle of incident light causing standing waves on the waveguide layer can be measured by the incident light entered into the ATR type waveguide mode resonance sensor. The waveguide formed of the NCD is formed by a hot filament chemical vapor deposition process using hydrocarbon-containing material gas. At this time, the crystal grain size of the NCD can be controlled by adjusting at least one among a substance temperature, a distance between a filament and a substance, and a hydrocarbon rate contained in the material gas.

Abstract:
PURPOSE: A broadband energy harvesting apparatus is provided to expand resonance frequency band on external vibration. CONSTITUTION: A mass(10) is installed to vibrate in a multidegree of freedom. Both ends of the mass are connected to vertical bars(51,52). Piezoelectrics(41,42) are installed to vibrate with the mass by reacting the vibration of the mass. Two cantilevers(31,32) are installed in parallel with each other at the same height. Bearings(61,62) are installed in the connection part of the mass and vertical bar.
