A smartphone controlled wireless data transmitting and inductive powering Power Lab-on-disc (PLoD) platform is developed based on 2.4 GHz Bluetooth and 205 kHz Qi techniques, respectively. A potentiostat is integrated on the PLoD platform, and amperometric measurements are performed. The wireless potentiostat can provide -3~3 V with 14-bit resolution for amperometry in a range of -300~300 μA with a readout noise floor of 1.2 μA (p-p) in a static condition. A 0~3000 rpm spinning test shows that a phosphate buffer saline (400 mV potential) baseline noise is proportional to spinning acceleration and deceleration.
