In this article nickel interdigital capacitors were fabricated on top of silicon substrates. The capacitance of the interdigital capacitor was optimized by coating the electrodes with a 60 nm layer of HfO2. An analytical solution of the capacitance was compared to electromagnetic simulations using COMSOL and with experimental measurements. https://www.roneverhart.com/Med-Mizer-AllCare-Scale-Fits-all-Med-Mizer-AllCare-Beds/
