Summary:This work investigates the properties of conductive circuits inkjet-printed onto the polycarbonate discs used in CD-based centrifugal microfluidics, contributing towards rapidly prototyped electronic systems in smart ubiquitous biosensors, which require sensitive and robust signal readout at low power and cost, and with wireless connectivity. A protocol for inkjet-printing electronic networks on CD substrates is developed. The circuit modeling of conductive tracks is discussed, and validated against experimental results. A design procedure is presented for reliably printing conductive networks with feature dimensions between 150 μm and 2 mm on CDs, and yielding electronic circuits operating with a bandwidth of 1 MHz.
