Abstract
A fluid storage device includes a container and a torsion sensor. The container stores a fluid to be agitated. The torsion sensor has a substrate and detects torsion of the substrate. The substrate has a first end inserted in the container and a second end fixed to the container or a housing.
Claims20
A fluid storage device comprising:
- a container configured to store a fluid;
- and
- a torsion sensor including a substrate and configured to detect a torsion of the substrate when the fluid is stirred,
- wherein the substrate has a first free end extending in the container and a second fixed end.

A fluid storage device comprising:
- a container configured to store a fluid;
- a torsion sensor including a substrate that has a first end fixed to at least one of the container and a housing of the fluid storage device and a second end disposed in the container;
- and
- a piezoelectric element coupled to the substrate and configured to generate an electric charge when the fluid is stirred in the container, such that the torsion sensor generates a voltage indicating a presence of the liquid in the container.
