Electrical impedance measurement of hydroxyapatite bovine scaffold based on thickness

Abstract

Hydroxyapatite (HA) scaffold is a biocompatible ceramic used as bone substitute material which widely developed nowadays. The pores that are owned can function as a new bone growth facility. The pores can affect the mechanical properties of HA scaffold. In order to enhance its mechanical properties, Dielectric Barrier Discharge (DBD) Plasma treatment method is expected to be a promised method to increase its compressive strength. The impedance value of HA Scaffold is an important factor that needs to be considered to determine the suitability of the HA Scaffold with plasma DBD treatment. In this study, the effect of thickness variation of HA scaffold on its impedance value was observed. The electrical impedance of HA scaffold was measured and characterized using Impedance Analyzer. The result showed that the impedance value of HA scaffold increases relative to the increases of HA scaffold thickness.Hydroxyapatite (HA) scaffold is a biocompatible ceramic used as bone substitute material which widely developed nowadays.
