In-plane and out-of-plane measurements of Rayleigh waves using EMATs for characterising surface cracks [PDF]
, 2012 Electromagnetic acoustic transducers (EMATs) have been used to measure the properties of Rayleigh waves in the vicinity of defects propagating at different angles to the sample surface, which are more representative of real defects than slots machined ...

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions
Advanced Materials, EarlyView.Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Magnetic phase transitions in Gd64Sc36 studied using non-contact ultrasonics [PDF]
, 2013 The speed and attenuation of ultrasound propagation can be used to determine material properties and identify phase transitions. Standard ultrasonic contact techniques are not always convenient due to the necessity of using couplant; however, recently ...

Scanning laser source and scanning laser detection techniques for different surface crack geometries [PDF]
, 2012 Standard test samples typically contain simulated defects such as slots machined normal to the surface. However, real defects will not always propagate in this manner; for example, rolling contact fatigue on rails propagates at around 25º to the surface,
