Fabrication and characterization of nonplanar microelectrode array circuits for use in arthroscopic diagnosis of cartilage diseases

Abstract — Editorial summary

This engineering paper describes the fabrication and characterization of a curved microelectrode array for measuring cartilage electrical responses during indentation. Platinum electrodes were incorporated into thin insulated circuits on spherical surfaces, allowing electrical recordings over the probe’s contact region. The researchers assessed electrical behaviour, including impedance and interactions between channels, and demonstrated cartilage measurements with the resulting array. The work addresses the manufacturing and instrumentation needed for an arthroscopic electromechanical probe. It is a device-development study and does not itself establish clinical diagnostic performance.
