“…The placement of the SPT needed to remain in an upright and fixed position that allowed for adequate tag bending, while minimizing negative effects on survival, tag retention, and growth to sturgeon. The tag placement and natural swimming motion of sturgeon would maximize the potential energy harvesting capabilities of the SPT, based on benchtop testing [25]. Even though 38% of fish retained their SPT after 595 days, results of the tag placement were successful in the remaining fish.…”

“…The SPT maintained an upright alignment along the flank, inside the dermis and hypodermis tissue for stability. However, some of these SPTs were bent and it is possible the bend would have broken the self-powering capability had the SPTs been functional, depending on the angle of the bend [25]. Sturgeon were located in a 600 L circular tank during the study, and may have turned and curved their bodies at an angle that caused the SPT to bend.…”

“…Biological aspects that influence the functionality of the SPT (i.e., the amount of power that can be harvested by the SPT) include the implantation location in the fish body and the fish's physical activity level and movement characteristics (e.g., degree of the body bending) [25]. Based on benchtop testing [25], the tagging technique would need to ensure that the SPT remains upright and in a fixed position inside the fish for the piezoelectric material of the SPT to bend sufficiently; in turn, effectively harvesting the mechanical energy required to power the tag. The tag bending would be generated by the natural swimming motion of the fish.…”

“…The objectives of our laboratory study were to evaluate the effects of the SPT on survival, tag retention, and growth of white sturgeon using a subdermal tagging technique designed for the SPT. The overall goal was to assess if the subdermal technique and tag placement would ensure proper functionality of the SPT (i.e., maximize the energy harvesting capabilities [25]), while minimizing negative tag effects to the fish, with the potential of developing a tagging protocol for use of the SPT in field studies.…”

Background A new technology for a self-powered acoustic tag (SPT) was developed for active tracking of juvenile fish, intended to avoid the typical battery life constraints associated with active telemetry technology. We performed a laboratory study to evaluate a subdermal tagging technique for the SPT and effects of the tag on survival, tag retention, and growth in juvenile white sturgeon (Acipenser transmontanus). Results Survival was associated with tag retention. White sturgeon implanted with the SPT (n = 30) had 93% survival and tag retention by day 28, 67% by day 101, and 38% by day 595 post-tagging. Sturgeon implanted with a passive integrated transponder (PIT) tag only (control group) had 96% survival and tag retention by day 28, and through day 101 post-tagging. Fish in the PIT group were repurposed after day 101, so no comparisons with this group were made at day 595 post-tagging. Specific growth rate (SGR) for fork length was a median of 0.25% day−1 by day 28 for the SPT group, which was significantly lower than the PIT group (median: 0.42% day−1; n = 27). The SPT and PIT groups had similar SGR fork length by day 101 post-tagging (0.22 and 0.25% day−1, respectively). SGR weight was also lower for the SPT group compared to the PIT group on day 28 (1.39 and 2.11% day−1, respectively), but the difference again dissipated by day 101 (0.79 and 0.88% day−1, respectively). Conclusion The tagging technique and placement of the SPT allowed the tag to remain upright along the flank of the sturgeon to ensure maximum battery output of the SPT; however, retention rates of the SPT were not ideal. We provided suggestions to improve the tagging technique. Suggestions included tagging fish that are > 400 mm FL, moving the incision location to extend the cavity and create a pocket for the placement of the SPT, and performing a quantitative wound-healing evaluation. Future studies are therefore recommended to evaluate these suggestions.

The applications of sensors in the aerospace industry are mostly concentrated in the middle and high frequencies, and low-frequency sensors often face the problems of low power and short working bandwidth. A lightweight, thin, high-power, low-frequency broadband transducer based on giant magnetostrictive material is designed. The design and optimization processes of the core components are introduced and analyzed emphatically. The finite element simulation results are validated by the PSV-100 laser vibration meter. Three basic configurations of the work panel are proposed, and the optimal configuration is determined by modal, acoustic, and vibration coupling analyses. Compared with the original configuration, it is found that the lowest resonant frequency of the optimal configuration is reduced by 24.6% and the highest resonant frequency within 2000 Hz is 1744.9 Hz, which is 54.2% higher than that of the original configuration. This greatly improves the vibration power and operating frequency range of the transducer. Then, the honeycomb structure is innovatively applied to the work panel, and it is verified that the honeycomb structure has a great effect on the vibration performance of the work panel. By optimizing the size of the honeycomb structure, it is determined that the honeycomb structure can improve the vibration power of the work panel to its maximum value when the distance between the half-opposite sides of the hexagon is H = 3.5 mm. It can reduce the resonant frequency of the work panel; the lowest resonant frequency is reduced by 12.8%. At the same time, the application of a honeycomb panel structure can reduce the weight of the transducer.

Energy harvesting, as a sustainable power source for implantable medical devices within the human body, is an intriguing area of research. The utilization of biochemical and biomechanical energy derived from the body offers a promising sustainable energy source. However, obtaining high power density in vivo is a challenge. Herein, energy harvesting is demonstrated using hybrid energy harvesters that simultaneously use mechanical energy from stretching and chemical energy from glucose. The hybrid energy harvesters operate as both biofuel cells (BFC) and mechano‐electrochemical energy harvesters (MEEH) within a single electrochemical cell. As a result, the hybrid energy harvesters offer a maximum power density of 17.8 W kg−1 and an average power density of 15.1 W kg−1. These values increase by 14.5% in maximum power density and 16.8% in average power density, compared to the sum of the power density obtained by mechanical stretching and glucose oxidation individually. Based on their improved performance and compact size, owing to the synergistic effect of the two electrochemical harvesting methods, these hybrid harvesters have the potential to be applied to implantable power sources.
