MEMS and Fiber Optics Sensor-Based Wearable Interface for Medical Applications

Abstract

In recent years, information technology has made remarkable advancement and found increasing, applications in various fields. In the medical field, computer is playing a more important role in assisting the disabled. However, the interface between the disabled and a computer is usually composed of push button and touch sensors that are difficult of use. This research aims to develop a more user-friendly wearable interface using a MEMS (Micro Electro Mechanical System) accelerometer and an optical fiber shape sensor that enable the disabled to use a computer more effectively. To demonstrate the application of this wearable interface, we developed several systems including a sensor fusion system for detecting motion of a human body, a communication device for the disabled to control computer keyboards and appliances, and a rehabilitation device referred to as a data glove. The effectiveness of the interface is demonstrated through several field tests.

A Personal Handheld Device to Support People with Life-Threatening Anaphylactic Allergies (PervaLaxis)

“…For example, helping blind people to navigate pavements and cross roads (Ross, 2001). In rehabilitation, accelerometers have been used to analyze motion to help patients to recover their mobility (Fukuda, Tanaka, Feng, & Ishimatsu, 2005). In addition, to usability, power consumption, and data security, factors such as aesthetics and wear-ability are important issues in such applications (Muhlsteff & Such, 2004).…”

Wearable interface for the physical disabled

“…Fukuda et al developed a MEMS and fiber optics sensor based interface for medical applications [13]. The interface attaches an accelerometer input device on the user's big toe to trigger the selected item on the screen.…”
