Passive Biotelemetric Detection of Tibial Debonding in Wireless Battery-Free Smart Knee Implants
SensorsAseptic loosening is the dominant failure mechanism in contemporary knee replacement surgery, but diagnostic techniques are poorly sensitive to the early stages of loosening and poorly specific in delineating aseptic cases from infections. Smart implants

Dual-Wavelength Mid-Infrared Generation Using Intracavity Stimulated Raman Scattering of PPLN
IEEE Photonics Journal, 2018 We report, to the best of our knowledge, the first demonstration of a continuous-wave, dual-wavelength (DW) mid-infrared optical parametric oscillator (OPO) based on the stimulated Raman scattering (SRS) effect of periodically poled lithium niobate (PPLN)

Non-destructive evaluation of concrete using a capacitive imaging technique : preliminary modelling and experiments [PDF]
, 2010 This paper describes the application of capacitive imaging to the inspection of concrete. A two-dimensional finite-element method was employed to model the electric field distribution from capacitive imaging probe, and how it interacts with concrete ...

Active osseointegration in an ex vivo porcine bone model
Frontiers in Bioengineering and BiotechnologyAchieving osseointegration is a fundamental requirement for many orthopaedic, oral, and craniofacial implants. Osseointegration typically takes three to 6 months, during which time implants are at risk of loosening.
