“…Revolutions in sensor technology are also being translated into a new generation of sensors to track marine life, with significantly reduced footprints and power requirements, including the capacity to harvest power from the environment, better accommodating animal anatomy and movement and containing significantly enhanced capacities for data storage and analysis. Examples of these revolutionary sensors include the "marine skin," a flexible-stretchable silicon-printed sensor system that brings the concept of wearable to marine animal tags (Nassar et al, 2018), new magnetic sensors to monitor animal behaviors in detail (Kaidarova et al, 2018a), and graphene-based flexible, ultrathin, and light salinity sensors to acquire oceanographic information (Kaidarova et al, 2018b).…”

Animal telemetry is a powerful tool for observing marine animals and the physical environments that they inhabit, from coastal and continental shelf ecosystems to polar seas and open oceans. Satellite-linked biologgers and networks of acoustic receivers allow animals to be reliably monitored over scales of tens of meters to thousands of kilometers, giving insight into their habitat use, home range size, the phenology of migratory patterns and the biotic and abiotic factors that drive their distributions. Furthermore, physical environmental variables can be collected using animals as autonomous sampling platforms, increasing spatial and temporal coverage of global oceanographic observation systems. The use of animal telemetry, therefore, has the capacity to provide measures from a suite of essential ocean variables (EOVs) for improved monitoring of Earth's oceans. Here we outline the design features of animal telemetry systems, describe current applications and their benefits and challenges, and discuss future directions. We describe new analytical techniques that improve our ability to not only quantify animal movements but to also provide a powerful framework for comparative studies across taxa. We discuss the application of animal telemetry and its capacity to collect biotic and abiotic data, how the data collected can be incorporated into ocean observing systems, and the role these data can play in improved ocean management.

“…Depending on the design of the PMMA molds, various customized elastic shapes and sizes can be obtained as shown in Fig.4. The magnetic particles are then aligned with a magnetic field prior to curing the PDMS, which was recently shown to increase the remanent magnetization by ~16% [5] and attributed to the alignment of an anisotropy axis with the field direction. Thus, a unidirectional magnetic field of 1.5 T was applied before curing at 90°C for an hour.…”

“…Thus, a unidirectional magnetic field of 1.5 T was applied before curing at 90°C for an hour. Carefully demolded composite magnets are also coated with Parylene C film of 2 μm thickness to enhance durability and simultaneously obtain corrosion resistance, and increased biocompatibility [5].…”

“…Such magnetic sensor systems are usually composed of neodymium magnets and a magnetic field sensor. A high tolerance of animals to magnetic fields [5] and the measurable magnetic properties exhibited by magnets in air and water [6] makes this approach particularly appealing to overcome the limitations of existing biologging devices. Here, we aim to improve animals' comfort and its free movement while their activity is being logged by developing a flexible, lightweight and minimally intrusive monitoring system, composed of NdFeB/PDMS composite magnets, magnetic sensors and a miniaturized wireless data acquisition unit.…”

A flexible, lightweight and minimally intrusive monitoring system has been developed to assess animals' behavioral responses. The system consists of wearable composite magnets and magnetic sensors integrated into a miniaturized wireless communication module with a flexible battery. The shape and size of the NdFeB-PDMS composite magnets are highly versatile, while the magnetic and mechanical properties can be tailored within a wide range by the powder concentration. The magnetic field of the composite magnet is sensed by a 3-axial magnetic sensor, and the measured data is wirelessly transmitted using Bluetooth low energy communication standard to a smartphone and dashboard. To withstand corrosive environments and enhance the durability the composite magnets are coated with 2 μm of Parylene C, while surface passivation of the wireless module is achieved with 5 μm of Parylene C. The system has been implemented for real-time monitoring of crabs, giant turtles, and giant clams, indicating its potential for novel and affordable animal monitoring applications. I.

Studies in the marine environment require devices to gather data in remote locations. These devices commonly use some form of data logging that require the user to retrieve the device after a period of time. This is not only a large effort, but often presents an unnecessary delay and risk in the event that the device malfunctions, goes missing or if the data collected is redundant. We propose a modular, remote and autonomous sensing solution that enables multi-sensor readout and wireless data communication, providing scientists with real time data. This sensor buoy is comprised of a primary module which is a data logger that connects to an online server via mobile network. The secondary portion is the hub that connects to an array of sensors that are customized to the needs of the marine scientists.
