We demonstrate a low-cost battery-free rapidly deployable and disposable patch for electrophysiological monitoring. This was performed by printing a stretchable AgInGa circuit over a temporary tattoo paper that is then transferred to a volunteer’s chest. The disposable patch BOM cost is less than 1$US, and can be rapidly customized with the presented printing technique. We showed that the electrodes printed with this method provide low skin-electrode impedance and excellent signal to noise ratio. The patch is then interfaced with a battery-free circuit for data acquisition, processing and communication via Bluetooth (Alberto et al., 2020).
