Marine Skin dives deeper for better monitoring

23.04.2019

A new and greatly improved version of an electronic tag, called Marine Skin, used for monitoring marine animals could revolutionize our ability to study sea life and its natural environment, say KAUST researchers.

Marine Skin is a thin, flexible, lightweight polymer-based material with integrated electronics which can track an animal's movement and diving behavior and the health of the surrounding marine environment. Early versions of the sensors, reported previously, proved their worth when glued onto the swimming crab, Portunus pelagicus.

The latest and much more robust version can operate at unprecedented depths and can also be attached to an animal using a noninvasive bracelet or jacket. This can, when necessary, avoid the need for any glues that might harm an animal's sensitive skin.

"The system can now operate down to a depth of 2 kilometers, which has never been achieved before by anyone," says Ph.D. student Sohail Shaikh of the KAUST team.

The sensitivity of the monitoring electronics has also been enhanced by up to 15 times. The data collected reveals a tagged animal's depth and the temperature and salinity of the surrounding water. Further development is planned to incorporate additional environmental sensing capabilities, such as measuring oxygen and carbon dioxide levels and precise geolocation tracking.

Shaikh reports that a major challenge in developing the enhancements was to make the system sufficiently robust to tolerate operating at much greater depths. The researchers also managed to reduce the size down to half that of the previous version.

Tests also showed improved performance, flexibility and durability when the skin was attached to different fish, including sea bass, sea bream and small goldfish. Lab tests in highly saline Red Sea water also demonstrated integrity through a full month's immersion and 10,000 extreme bending cycles.

"Marine skin is a unique and groundbreaking innovation in wearable technology for marine animals," says Muhammad Mustafa Hussain, whose research group has developed the system in collaboration with Carlos Duarte's group, also at KAUST.

Professor Hussain adds that Marine Skin outperforms all existing alternatives while emphasizing that ongoing development work will continue to enhance the sensing capacities, overall performance, reliability and affordability.

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
