This paper presents the concept and design of a system that embeds piezoelectric sensors to measure voltage mechanical load applied it. COMSOL Multiphysics, finite element simulation tool, was used analyze data find possible fingerprint changes. The sensors’ readings were affected by surface structure with different magnitudes speeds. analyzed show effect position mass on indicates possibility ...

Introduction: Bone tissue has a limited ability for regeneration; critically sized defects cannot self-heal and require medical intervention. Bone tissue engineering (TE) circumvents this issue by growing replacement bone tissue from the patient's own cells inside scaffolds. TE scaffolds are porous constructs that act as a support structure during bone regeneration and helps cells attach and pr...

Abstract In embedded systems that necessarily require a steady source of power and (or) attaches to sensor(s), there are opportunities mix small batteries supply such power. The aim this research is optimize the geometry shape piezoelectric cantilevers harvest more Several cantilever geometries with various shapes (rectangular, triangular, circular, trapezoidal cross section) tested in COMSOL m...
