A (a) The sensor designed by Mishra et al. for simultaneous detection of THC and alcohol. (b) The image of ring-shaped sensor. (c) The ring polymeric case with the embedded electronics and replaceable screen-printed electrodes section. B Mechanisms of THC and alcohol detection using the ring sensor. The voltammogram for the detection of THC (in red) and the amperogram of alcohol detection is also illustrated (in blue). Taken from (Mishra et al. 2020) with permission from Elsevier (Copyright 2020)
