In this work, we present a walking context analysis for the electronic navigation of visually impaired persons. The walking context is defined as the safety level of the walking condition. An ext ... Read More

We demonstrated a Si-based concave micromirror array for cell trapping that was fabricated by XeF2 vapor etching. We also examined the optical properties of the focal image of each concave microm ... Read More

Human gait recognition is very important for controlling exoskeletons and achieving smooth transformations. Gait information must be obtained accurately. Therefore, in order to accurately control ... Read More

Mixed-potential gas sensors with an anhydrous electrolyte consisting of zinc metaphosphate glass and benzimidazole were fabricated for the detection of hydrogen. Using a combination of similar se ... Read More

Indium-doped ZnO/Cu-graphene thin films were successfully synthesized by a hydrothermal method at 90 °C for 6 h. The crystalline structure, elementary compositions, morphologies, and photolumine ... Read More

Graphene-based sensors are mostly studied in terms of their responses to inorganic gases such as various nitrogen oxides or ozone. In this work, chemically derived graphene (CDG) is assessed in t ... Read More
