During his secondment at partner EEM, Paulo Pedrosa was joined by Carlos Fonseca, also from partner UPORTO. The purpose of the secondment of Paulo Pedrosa to EEM was to discuss the optimization of the coating procedure of the multipin dry electrodes. The discussion focused on several key issues: 1) the deformation of the base plates; 2) possible improvement of the fixation procedure; 3) the scaling-up of the coating procedure to meet industrial production criteria.
