Abstract
A surface tension sensor detects alcohol in solution by determining the transition of a liquid droplet from a non-wetted to a wetted state. Results from testing commercial wines are presented along with the fabrication of electrospun two-layer polymeric sensor arrays, which exhibit controlled wettability.
