The Brain Computer Interface (BCI) is a user interface that helps people with severe physical disabilities to communicate with others or to interact with their surroundings by using their brain waves to control devices. However, almost all conventional studies about stimulus-driven BCI focused on a visual modality. Until recently, there still haven't had useful tools to help blind people who suffer...
People with severe physical disabilities could operate computerized devices (such as: eye-tracker, visual stimulation BCI, etc.) based on brain activity and without muscle movement. But it's hard for the blind people with severe physical disabilities (e.g., blind amyotrophic lateral sclerosis (ALS)) to use these computerized devices by their eyes. If these people could use their normal brain and auditory...
A linear-response capacitive tactile sensor is presented in this work. The sensor was fabricated by the TSMC 0.35 μ m CMOS process and our self-developed MEMS post-process. The structure of the sensor consisted of one pair of parallel electrodes, with the central part of the membrane electrode hollowed out. A pillar with four beams at each side was set at the center to support the membrane electrode...
Scaling is a key issue for resistive switching (RS) memory before commercialization. In this paper, for the first time, we reveal the impact of electrode diffusion on the device performance as the thickness of RS material scaling. Serious deterioration of on/off ratio and device yield was observed when the material scaled below 3 nm. A new method of two-step electrode deposition accompanied with re-oxidization...
The pulse echo non-destructive evaluation (NDE) technique has been used within the automotive industry for many years, but this is an offline approach, where tests are carried out after welding. Recent research has been carried out to monitor spot welding online. This paper proposes a portable online, real time, through-transmission, continuous wave ultrasonic non-destructive evaluation system for...
