Abstract: There is provided a force sensor including a substrate and a polymer material layer. The substrate has a circuit layout that includes a first electrode and a second electrode configured to form a capacitor therebetween. The polymer material layer covers at least on a space between the first electrode and the second electrode, and is used to change capacitance of the capacitor while being pressed. The force sensor is arranged inside a stem of an earphone for detecting the user input.

Abstract: A sprayer includes: a container; a passage including a transparent window, a first opening, a second opening and a resonator, wherein when liquid in the container is passed through the resonator via the first opening, the liquid is emitted as a gas via the second opening; and a removable detection unit disposed outside of the passage. The removable detection unit includes: a light source for illuminating the gas in the passage; an optical sensor disposed to detect a parameter of light reflected by the gas; and a processor coupled to the optical sensor for stopping the resonator from generating the gas when the parameter is below a threshold. The passage further includes a cavity disposed on a bottom surface of the passage in front of the optical sensor, wherein when the gas in the passage contacts the bottom surface, resultant water vapour will enter the cavity.
