Force control is very crucial in nanoimprint lithography (NIL). It is necessary to develop a high-performance force sensor to provide real-time force feedback for the control process. Due to the unique procedure of NIL, the developed force sensor should include a high sensitivity, broad bandwidth, and large measurable range. However, these characteristics are normally conflicting in nature and cannot...
Movement disorder in lower extremity has been a major concern for the elder worldwide. Early diagnosis and effective therapy monitoring is an important prerequisite to treat patients and reduce health care costs. Objective and non-invasive assessment strategies are an urgent need in order to achieve this goal. In this study, we apply a wearable, lightweight and easy applicable sensor based gait analysis...
Plantar pressure distribution and acceleration measurements are important to detect walking postures and states. This paper presents an in-shoe measurement and analysis system to do the detection. In-shoe information is acquired by the circuit board which is attached to the human's shank and transmitted to the remote receiver wirelessly. A real-time display and analysis software is developed. Experiments...
Multi-axis force sensors have been investigated for several decades, but existing multi-axis force sensors are limited in range by their resolutions. They are sensitive to noises, when subjected to signal draft, and they are still relatively expensive. To address these problems, this paper presents the conceptual design of a novel two-dimensional force sensor capable of resolving two perpendicular...
