Liquid Mass Sensing Using Resonating Microplates under Harsh Drop and Spray Conditions

Figure 6

(a) Mass of the liquid (water/ethanol) deposited on the plate as a function of the shift in resonant frequency, for both and modes. (b) Estimated mass of water on the plate as a function of time, for water drip (Figure 4). (c) Mass of ethanol on the plate as a function of time, for ethanol spray (Figure 5).
