Fracture healing monitored with strain gauges

Nonlinearity and Hysteresis of Resonant Strain Gauges

Nonlinearity and hysteresis effects of electrostatically activated, voltage driven resonant microbridges have been studied theoretically and experimentally. It is shown, that, in order to avoid vibration instability and hysteresis to occur, the choices of the ax . and d.c. driving voltages and of the quality factor of a resonator, with a given geometry and choice of materials, are limited by a ...

Fracture healing

Those of us who have experienced a significant fracture likely recall first the pain of the injury, then we often focus our attention on the prospect of time in a cast or other form of extended immobilization. We imagine the discomfort and limitations that will ensue, and after all else settles down, we often wonder, “How strong are my bones anyway, and will I fracture again?” Nature, on the o...
