A new method is presented for smartphone-based impedance spectroscopy, especially fine-tuned for biomimetic sensor readout. Complete user control is given by means of an app while the on-board audio hardware of the smartphone or tablet PC is used to perform impedance measurements. This considerably limits the required external hardware. Disposable test strips can be mounted for convenient readout of various sensors. The system is verified on passive components and a synthetic molecularly imprinted polymer histamine sensor. The prototype design could prove a useful step toward the development of home-diagnostics biosensing applications.
