Semi-Conductor Strain Gaging
In addition to foil strain gage applications support and foil strain gage transducer design and manufacture capabilities, HITEC offers extensive expertise in the semi-conductor strain gage field.
Semi-conductor strain gages are considered for an application where low strain conditions or severe overload requirements are present. In areas where a foil strain gage is not suitable or perhaps ideal, a semi-conductor strain gage offers advantages with its high gage factor. Semi-conductor strain gages can also be utilized where extreme space constraints exist, low loads exist or where a high signal to noise ratio is required.

Recent applications involving semi-conductor strain gages include:
- Multi-axis quadraped - semi-conductor strain gages were used for feedback and improvement in robotic motion actuation techniqies. Due to low loads, semi-conductor strain gages were employed in a full bridge configuration for force feedback resulting in a successful study
- Phalange sensors - this requirement was to measure forces in an humanoid hand. Small in-situ space constraints for the gage area as well as forces/strain involved, semi-conductor strain gages were chosen to make up a phalange sensor to ultimately emulate a hand capable of performing mechanical tasks.
- Prosthetic knee transducers - our design team was called upon to help select proper semi-conductor strain gages as well as devise the temperature compensation techniques required for production units
- Trailer axle hubs - semi-conductor strain gages were utilized for validating and verifying the process that determines axle bearing preload. The component itself was instrumented with semi-conductor strain gages in a full bridge configuration as the solution given low strain levels.
