AbstractStrain sensors have been fabricated by depositing platinum nanoparticles between interdigitated gold electrodes on oxidised silicon substrate. A significant improvement in strain sensitivity is achieved with a gauge factor in excess of 700, which is two orders of magnitude higher than continuous metallic films and five times higher than ...

Fiber Bragg Grating Sensors for Pile Jacking Monitoring in Clay Soil
The small deformation of the model pile in a pile jacking test makes its accurate measurement very difficult. Based on the installation method of clamping at both ends, a sensitized miniature fiber Bragg grating (FBG) strain sensor was developed to ...

Compliant Mechanism-Based Sensor for Large Strain Measurements Employing Fiber Optics
We propose a sensor design for measurement of large strains where direct application of a fiber optic strain gauge is impossible due to the stiffness mismatch between the optical fiber and the structure under test. The sensor design is based on a rhombus

Metamaterial-based wireless strain sensors [PDF]
We proposed and demonstrated metamaterial-based strain sensors that are highly sensitive to mechanical deformation. Their resonance frequency shift is correlated with the surface strain of our test material and the strain data are reported telemetrically.

Piezotronic effect in AlGaN/AlN/GaN heterojunction nanowires used as a flexible strain sensor
1D semiconductor nanowires (NWs) have been extensively studied in recent years due to the predominant mechanical flexibility caused by a large surface-to-volume ratio and unique electrical and optical properties induced by the 1D quantum confinement ...

Application of Robust, Packaged Long-Period Fiber Grating for Strain Measurement
This paper proposes an optical fiber strain sensor based on packaged long-period fiber gratings (PLPFG) which is fabricated by the micro-electromechanical systems (MEMS) process and packaged with poly-dimethylsiloxane (PDMS) polymer materials.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.
