Abstract Aiming at the control of a powered prosthetic hand, this paper compares methods for the classification of intended hand motions using muscle bulging patterns caused by muscle contraction. Two sheets of Polyvinylidene Difluoride (PVDF) film were used as sensors to detect the muscle bulging on the forearm caused by intended hand motions. A neural […]
Abstract In the fields of medical and sports science, it is required to evaluate muscle activity qualitatively and quantitatively. Currently, mechanomyogram (MMG) that can reflect the mechanical activity of muscle fibers is attracting attention. The purpose of this study is to develop a sensor that can measure MMG during exercise. In this study, a small […]
Abstract A social issue that leads to the safety and security of people is the network that monitors the safety of people living alone in remote areas. Various research and developments of indoor human activity recognition using IoT sensor nodes have been conducted in recent years. In this research, we focus on turning on and […]
Abstract Femtosecond double optical pulse experiments with nanosecond time delay were conducted in air. Terahertz pulses were generated from laser plasmas produced by the irradiation with the main pulses on shockwave excited by the pre-pulse illumination. Intensity of the terahertz pulses depends on the time difference Δt and relative position Δy between the pre- and […]
Abstract The purpose of this study is to realize a grasp force measurement of forceps for robotic surgery systems. Generally, surgical robot forceps is actuated by traction wire, and we have suggested a newly force sensing system by measuring the wire expansion utilizing micro displacement sensors. For measuring the elongation of the wire, the white-light […]
Abstract There is a growing interest to introduce energy-saving algorithms which balance energy efficiency with residents’ comfortability into a building energy management system (BEMS). However, the following issues hinder penetration of the energy-saving algorithms into markets: difficulties both in embedding the algorithms into the BEMS, and in turning the algorithms suitably to fit varieties of […]
Abstract Text input, which is essential for a variety of applications, is one of the most difficult operations for older people. So, we propose a prototype to automatically detect and input text from a natural image taken from a user’s smartphone. For the evaluation of the system, 232 photo data taken by the actual people […]
Abstract This paper presents a method for forecasting the change direction of nonstationary time series using the improved leading indicator. The leading indicator is a method developed by Ehlers that translates a time series mathematically in the future direction with respect to the time axis and calculates the leading value of the time series. However, […]
Abstract A polyclonal antibody against the analog of piperine, which is a typical pungent taste substance, was produced, and its binding ability to piperine was evaluated using a surface plasmon resonance sensor. The antibody was labeled with glucose oxidase (GOx), and the hydrogen ions produced by the enzymatic reaction were measured at a lipid polymer […]
Abstract Advances in microfabrication technology have enabled electron beam lithography (EB lithography) systems to produce microfabrication on the order of 10 of nanometers. Using this technology, we have fabricated nanogap electrodes that can generate large electric fields at low voltages. The gap between the tips of the fabricated electrodes is 100 nm, and the curvature of […]
