Numerical Study on Electromechanics in Cartilage Tissue with Respect to Its Electrical Properties

Abdul Razzaq Farooqi et al. Tissue Eng Part B Rev. 2019 Apr.

Abstract

The presented research summarizes the basic models with mathematical description regarding electrical behavior of the cartilage tissue. A preliminary numerical study involving electromechanical transduction in bovine cartilage tissue sample has been carried out using an open source finite element software. This research will provide scope for future research regarding electrical behavior of the cartilage tissue using open source software.

Keywords: cartilage; electrical properties; electrical stimulation; electromechanical transduction; streaming potential; tissue engineering.

(A) Electrical stimulation, (B) confined compression, (C) unconfined compression, (D) indentation, (E) permeation configuration, (F) electro-osmosis/diffusion (without Vi). ΔP is the change in pressure, Δδ is the change in thickness of the cartilage sample, ΔVi and ΔVo are the change in input and output voltages, respectively.
