Through the Eyes of Underwater Creatures: Wearable, Whole-Body Sensing Networks

Horseshoe Crab
Michael Bartlett will craft wearable, whole-body noticing networks with a Young Investigator Award from the Office of Naval Research.
The horseshoe crab is often referred to as a “living fossil” since its advancement has actually been essentially stagnant for countless years. Despite its absence of development over the long term, however, the crab has a special sensory system with a network of numerous “eyes,” a few of which are photoreceptors that compare dark and light.
With funding from the Office of Naval Research, mechanical engineering Assistant Professor Michael Bartlett is putting a bio-inspired electronic variation of that sensory system to operate in a series of soft electronic devices to be worn by people.

To establish the technology, Bartlett will source principles from his abundant background in soft electronics. The lab has given that adjusted these skin-like electronic devices for use in soft wireless charging devices and robust, self-healing electrical circuits. For this sensor range, the group is reconstructing numerous of the linked stiff parts as soft electronic devices, accommodating optimal variety of motion and convenience.
” Ultimately, we intend to significantly advance basic knowledge of soft sensing architectures, allowing wearable platforms that imitate underwater organisms and provide real-time sensing unit information to a user for a better understanding of their environment,” Bartlett said. “What if you could pick up the environment all around you?

Bartlett got a 2021 Young Investigator Program award from the Office of Naval Researchs Littoral Geosciences and Optics program for his efforts to equate the physiology of undersea animals into next-generation sensing unit technology.

Bartlett and his group in the Soft Materials and Structures Lab are captivated by creatures like the horseshoe octopus, mantis, and crab shrimp because of the variety of natural sensing units utilized by the animals. From the 10 “eyes” dispersed across the shell on the horseshoe crab to the articulating compound eyes of the mantis shrimp, these organisms have the methods to adapt their behavior based on a myriad info passed on to their brains about their environment.
” These organisms see their world really in a different way, being able to take in numerous pieces of info to evaluate their environment,” Bartlett said. “This situational awareness is actually impressive and got us considering how we can create sensing units to boost awareness for human beings.”
Bartletts technique uses the concept of a detailed cognitive system to an integrated electronic network. Inspired by the system through which a horseshoe crabs motion is informed by its lots of eyes, the team will equip a wearable device with miniaturized sensors that will process the environment in motion.
Data fed from the sensing units will be combined to offer a more robust image of a topics environments. The wearable networks main processor will utilize its linked sensing units to provide sophisticated visual, sound, and distance capabilities to navigate prospective issues.

To develop the innovation, Bartlett will source ideas from his rich background in soft electronic devices. In a current project, he developed polymer composites with liquid metal additions– gadgets that replace traditional wires and stiff products with highly flexible products sandwiched together. These unique devices feel like skin, however bring an electrical present. The lab has because adapted these skin-like electronics for usage in soft cordless charging gadgets and robust, self-healing electrical circuits. For this sensor selection, the group is reconstructing numerous of the linked rigid elements as soft electronics, accommodating optimal series of movement and convenience.
” With the advancement of soft electronic devices, we see the prospective to create wearable gadgets that seem like a 2nd skin and offer varied data to the user,” Bartlett said. “This could improve sensory perception in a way that allows for a better understanding of somebodys environment.”
Bartlett thinks that the “second skin” nature of the technology might equate to next-generation diving fits made of soft-matter parts more like natural tissue– over rigid, heavy gear– with a higher variety of motion and faster motor action.
” Ultimately, we aim to substantially advance fundamental understanding of soft sensing architectures, making it possible for wearable platforms that mimic undersea organisms and supply real-time sensor information to a user for a better understanding of their environment,” Bartlett said. “What if you could sense the environment all around you? It would be like having eyes in the back of your head.”
