Force sensor method and construction
First Claim
1. A method of making a force sensor, said force sensor being particularly sensitive to forces applied along a predetermined axis, of the type including a force-receiving membrane deformable by an applied force to be sensed, said method comprising:
- providing the force sensor with a body of a liquid, and with a second membrane separated from said force-receiving membrane by said body of liquid;
applying the force to be sensed to the center of said force-receiving membrane to thereby pressurize said liquid according to the magnitude and axis of the force applied to said force-receiving membrane; and
measuring the deformation of said second membrane.

6. A method of sensing a force by means of a sensor of the type including a deformable membrane, said method comprising:
-
providing the sensor with a chamber which is filled with a liquid and which is closed at one side by said deformable membrane;
applying the force to be sensed to the central region of said deformable membrane, to thereby pressurize said liquid according to the magnitude and the axis of the force applied to said deformable membrane; and
measuring the pressure of the liquid in said chamber. - View Dependent Claims (7, 8, 9, 10, 11)

12. A force sensor particularly sensitive to forces applied along a predetermined axis, comprising:
-
a housing having a chamber filled with a liquid;
a deformable membrane closing one side of said chamber such that the inner surface of the membrane contacts said liquid, and the outer surface of said membrane is adapted to receive at its center region the force to be sensed, to thereby pressurize said liquid according to the magnitude and axis of the force applied to said central region of the membrane; and
means for measuring the pressure of the liquid in said chamber. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
