# Bat-Inspired Sonar Systems This Horseshoe Bat-Inspired Sonar is Compact and Efficient By Rahul Kalvapalle | Published 2015-05-25 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/sonar-system References: [gizmag](http://www.gizmag.com/horseshoe-bat-inspired-sonar-system/37640/) & [vtnews.vt.edu](http://www.vtnews.vt.edu/) A team of engineers at [Virginia Tech](https://www.trendhunter.com/trends/galmed) are developing a sonar system that emulates the system utilized by bats. Once refined, this system is expected to be a more efficient and compact alternative to man-made sonar. Horshoebats emit squeaks from their noses, which allows them to change the characteristics of said squeaks to suit different purposes. One particular squeak allows them to detect frequency shifts caused by the fluttering wings of insects. The researchers replicated this system by analyzing the nose and ear movements of horseshoe bats before creating computer models and building a prototype. The contraption is around 2.5 times the size of a typical horseshoe bat and uses four motors to move its ears and nose. This is the first sonar system to features a dynamic emitter (the nose) and dynamic receivers (the two ears), and is set to be implemented on a [drone](https://www.trendhunter.com/trends/swimming-robots-1) to see if it can aid flight motion. ## Trend Insights (Trend Hunter) - Score: 1.7/10 - Popularity: 24% | Activity: 18% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Science](https://www.trendhunter.com/science) ## Key Themes ### Key Themes Behind This Trend - **Compact Sonar Systems:** The development of bat-inspired sonar systems presents an opportunity to create more compact and efficient sonar technology. - **Dynamic Emitter and Receivers:** The integration of dynamic emitter and receivers in sonar systems opens up possibilities for enhanced functionality and performance. - **Bio-inspired Technology:** The application of bio-inspired technology, such as bat sonar systems, can lead to innovative solutions in various industries. ### Where This Applies - **Military and Defense:** The military and defense industry can leverage bat-inspired sonar systems to enhance surveillance and detection capabilities. - **Aviation and Aerospace:** The aviation and aerospace industry can explore the use of compact and efficient sonar systems for unmanned aerial vehicles (UAVs) to improve flight capabilities. - **Maritime and Underwater Exploration:** The maritime and underwater exploration industry can benefit from the implementation of dynamic emitter and receiver sonar systems for improved detection and navigation. ## Related on Trend Hunter - [Miniature Flying Robots](https://www.trendhunter.com/trends/tiny-robot.md) - [Biomimicry Bird-Like Drones](https://www.trendhunter.com/trends/bionic-bird-xfly.md) - [Bionic Fishing-Tracking Robots](https://www.trendhunter.com/trends/bionic-positioning-fish.md) - [Facial-Tracking Sonar Glasses](https://www.trendhunter.com/trends/echospeech.md) - [Bug-Like Flying Robots](https://www.trendhunter.com/trends/micro-insect-robot.md) - [Avian African Aircraft Concepts](https://www.trendhunter.com/trends/aircraft-concepts.md) - [Water-Mapping Autonomous Boats](https://www.trendhunter.com/trends/watermapping-autonomous-boats.md) - [Computational Audio Recording Devices](https://www.trendhunter.com/trends/audio-recorder-concept.md) - [Semantic Hearing Headphones](https://www.trendhunter.com/trends/hearvana-ai.md)
