Paper Title:
Development of Pore Pressure Measurement System in Lacunocanalicular Network of Trabeculae Using MEMS Based Micro-Pressure Transducer
  Abstract

Experimental measurement of pore pressure generation in lacunocanalicular network of trabeculae is never measured, although the characteristics could be important for bone remodeling. In this study, the pore pressure generation in micro-trabecular specimens within the elastic range was measured in vitro using a specially designed micro-experimental setup and a MEMS based micro-pressure transducer. Then, a quasi-static loading (9㎛/min) was applied up to the strain of 0.4 % with measuring pore pressure generations in the undrained and drained conditions. 49.2 ± 4.45 KPa of pore pressure generation at the 0.4% strain was found in the undrained condition. In contrast, no pore pressure generation was measured in the drained condition. The result could let us know the amount of a possible maximum pore pressure generation in lacunocanalicular network of trabeculae within the elastic range.
