This provides real-time feedback to surgeons, improving the accuracy and safety of procedures.
Challenges in the FBG Displacement Sensor Market
Despite the promising growth of the FBG displacement sensor market, there are several challenges that could impact its adoption and development. Addressing these challenges will be crucial for realizing the full potential of this technology.
1. High Initial Cost
One of the primary barriers to the widespread adoption of FBG displacement sensors is their high initial cost. The advanced technology behind these sensors, along with the precision required for manufacturing, results in a higher price point compared to traditional displacement sensors. For small and medium-sized enterprises (SMEs) or industries with limited budgets, the upfront investment required for FBG sensor systems can be a significant deterrent.
2. Complex Installation and Calibration
While FBG displacement sensors are highly accurate, they require careful installation and calibration to function optimally. Unlike traditional displacement sensors, FBG sensors often need to be integrated with other optical equipment, such as light sources, detectors, and data acquisition systems. This can add complexity to the installation process and may require specialized knowledge and skills. The calibration process also requires precise handling to ensure accurate measurements over time.
3. Sensitivity to Environmental Factors
FBG displacement sensors are generally known for their resistance to environmental factors, but they can still be affected by extreme conditions such as temperature fluctuations, pressure, and vibration. These external factors can cause slight errors in measurements if not properly compensated for. Engineers need to account for these environmental influences when designing and deploying FBG sensor systems, which can add complexity to their use in certain applications.
