This paper first analyzes the soft-sensor technology and temperature measurement technology used in recent soft measurements, focuses on the accuracy and efficiency requirements of soft measurement in slab surface temperature detection. In this paper, we collects images noise processes of continuous casting slabs, and uses component-based OTSU segmentation method to extract the slab area and th...

The wavefront of an injection-seeded soft x-ray laser beam generated by amplification of high-harmonic pulses in a λ=18.9 nm molybdenum plasma amplifier was measured by a Hartmann wavefront sensor with an accuracy of λ/32 root mean square (rms). A significant improvement in wavefront aberrations of 0.51±0.03λ rms to 0.23±0.01λ rms was observed as a function of plasma column length. The variatio...

We demonstrate a technique for tapering periodically an all-solid soft glass fiber, consisting of two types of lead silicate glasses, by the use of a focused CO(2) laser beam and investigate the bend sensing applications of the periodically tapered soft glass fiber. Such a soft glass fiber with periodic microtapers could be used to develop promising bend sensors with a sensitivity of -27.75 μW/...

Soft and stretchable sensors of strain are important for human–machine interfaces, soft robotics, electronic skins. However, generally cannot distinguish in-plane from normal stress. For example, stretching a sensor often gives similar signal to pressing the sensor. To solve this problem, liquid metal (LM)-interdigitated capacitive that is insensitive stress introduced. The contains LM-interdig...

Wireless Sensor Network, or WSN, has a large amount of applications such as target tracking, health monitoring and security etc. These applications have been proposed for mobile wireless Sensor Network (MWSN). Mobile Sensor node transmits the data with a fixed node in real time applications. MWSN uses various handover techniques which support the mobility of different coordinators. IEEE 802.15....

Flexible pressure sensors are increasingly being used in medical and non-medical applications, and particularly in innovative health monitoring. Their efficacy in medical applications such as compression therapy depends on the accuracy and repeatability of their output, which in turn depend on factors such as sensor type, shape, pressure range, and conformability of the sensor to the body surfa...

This paper aims at developing a force-guided microassembly technology with in-situ flexible polyvinylidene fluoride (PVDF) beam force sensing and hybrid force/position control based on an infinite dimensional model of the flexible sensor structure. Besides the designed 1-D PVDF cantilever based microforce sensor, as the soft sensor structure itself is installed at the free end of micromanipulat...

The present paper presents a finite element model and analysis for the interaction between a piezoresistive tactile sensor and biological tissues. The tactile sensor is proposed for use in minimally invasive surgery to deliver tactile information of biological tissues to surgeons. The proposed sensor measures the relative hardness of soft contact objects as well as the contact force. Silicone r...

During dental sinus lift surgery, it is important to monitor the thickness of the remaining maxilla to avoid perforating the sinus membrane. Therefore, a sensor should be integrated into ultrasonic dental tools to prevent undesirable damage. This paper presents a piezoelectric (PZT) sensor installed in an ultrasonic transducer to measure the stiffness of high and low materials. Four design type...

We describe a new tactile sensor for use in dexterous manipulation and telemanipulation. The sensor consists of an array of curvature-measuring elements embedded in a compliant membrane. The resulting sensor is inexpensive and robust, and can be used in robotic hands with soft fingertips for object handling and exploration. The curvature measurements provide information for manipulation plannin...
