3d Shape Measuring Instruments Using High Stiffness Vibration Touch Sensor
In this paper, a novel method to determine the shape of a 3D object is proposed. Instead of a flexible conventional touch probe, a high-stiffness vibration touch sensor was developed. The proposed sensor consisted of a piezo-electric device and thin probe, and generated feedback voltage according to the relative distance from the object. The structure of this sensor is simple, so that it can wi...
متن کاملMeasuring Arterial Stiffness Using Photoplethysmogram
Monitoring of the arterial condition promises an advantage in detection of any abnormalities occurred among diabetic patients. In this study, the characteristic of photoplethysmogram (PPG) has been investigated non-invasively to measure the status of arterial stiffness. A total of 101 Type 2 diabetic patients, aged 50 to 70 year were participated in this study. The patients divided into two gro...
متن کاملQuantitative measuring of pearlite in carbon steels using electromagnetic sensor
Non-destructive Eddy current (EC) technique has long been used to detect discontinuities in materials. Recently, its application has been extended to characterize materials microstructure. In order to identify different microstructures, four plain carbon steel bars with different chemical compositions (AISI 1015, 1035, 1045 and 1080) were used in annealed condition. The pearlite percentage, car...
متن کاملAdaptive Tunable Vibration Absorber using Shape Memory Alloy
This study presents a new approach to control the nonlinear dynamics of an adaptive absorber using shape memory alloy (SMA) element. Shape memory alloys are classified as smart materials that can remember their original shape after deformation. Stress and temperature-induced phase transformations are two typical behaviors of shape memory alloys. Changing the stiffness associated with phase tran...
متن کاملDynamic Tire Pressure Sensor for Measuring Ground Vibration
This work presents a convenient and non-contact acoustic sensing approach for measuring ground vibration. This approach, which uses an instantaneous dynamic tire pressure sensor (DTPS), possesses the capability to replace the accelerometer or directional microphone currently being used for inspecting pavement conditions. By measuring dynamic pressure changes inside the tire, ground vibration ca...
