What is this:
This research focuses on shape sensing for soft robotics inside of the silicone octopus tentacle model. Specifically they used Fiber Bragg Grating (FBG) sensors.
It explores how FBG sensors can track the bending and deformation of the tentacle when actuated by air pressure.
What is FBG:
type of optical sensor embedded in optical fibers that reflects specific wavelengths of light while allowing others to pass. It is widely used for strain, temperature, and shape sensing in various applications, including soft robotics, medical devices, and structural health monitoring. ( Based on ChatGPT)
Potential Applications:
Surgical Robots, wearable sensors, and anything irregularly shaped that needs to be grasped and manipulated
How it works:
Like an octopus! But with interpolation algorithm to calculate how much it needs to bend
system measures wavelength shifts in the optical fiber to calculate curvature
Why interesting:
Bio-inspired Design
Real time active sensing
