Wireless Capacitive Load Cell Device

A device for providing wireless load measurements, said device comprising:

• a. A two-component strain member composed of a spring body featuring one or more cantilever beams and a force transduction plate containing an indenter, wherein said force transduction plate deforms the spring body out of a state of rest when a load is applied, and the displacement of the force transduction plate is mechanically restricted to prevent overloading;
• b. A capacitive transducer for monitoring relative deformation of the force transduction plate, wherein said capacitive transducer is secured to a fixed region of the cantilever spring body, and the indenter within the force transduction plate displaces vertically into contact with the capacitive transducer, wherein said capacitive transducer generates an output signal in in response to an applied load acting on the spring body;
• c. A polymeric and/or elastomeric coating to an external surface of the capacitive transducer;
• d. One or more accelerometer embedded within said wireless load cell, said one or more accelerometer generates an output signal in response to dynamic displacement of said wireless load cell;
• e. At least one signal conditioning device coupled with said capacitive transducer, and at least one accelerometer, wherein said signal conditioning device being able to receive signal data from multiple sensors and to send a signal analogous with the output signal of the capacitive transducer and at least one or more accelerometers;
• and
• f. At least one microcontroller unit that processes the output signal data from the signal conditioner and prepares it for digital wireless transmission.
