# Multipurpose Energy-Generating Sheets The Super Slim and Flexible Device Turns Flags Into Speakers By Alyson Wyers | Published 2017-05-27 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/flexible-device References: [springwise](https://www.springwise.com/scientists-create-paper-thin-device-turns-flags-loudspeakers/) & [msu.edu](https://msu.edu/) Scientists from [Michigan State University](https://www.trendhunter.com/trends/AI-biomechanical-coaching) (MSU) designed this extremely thin and flexible device, which is capable of turning flags into loudspeakers. The creation generates electrical energy from mechanical or human movement and can also capture vibrations from sound. Known as FENG, the ferroelectret nanogenerator has multiple uses, like being able to [power a keyboard](https://www.trendhunter.com/trends/lenovo-800-selfcharging-bluetooth-keyboard), LCD touchscreen and LED light. In the future, it could also lead to voice-activated security patches or even talking newspapers. Funded by the [National Science Foundation](https://www.trendhunter.com/trends/upcycled-facemasks), the paper thin FENG fabric consists of an electrically charged silicone wafer made out of eco-friendly elements like silver, polypropylene ferroelecret and polyimide. The flexible device is an example of a state of the art invention that makes commonplace, everyday items multifunctional. ## Trend Insights (Trend Hunter) - Score: 2.3/10 - Popularity: 39% | Activity: 23% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Science](https://www.trendhunter.com/science) ## Key Themes ### What Makes This Trend Stand Out - **Multipurpose Energy-generating Devices:** Opportunity to create innovative devices that generate electrical energy from mechanical or human movement. - **Flexible and Thin Electronics:** Potential for the development of slim and flexible devices that can be used in various applications. - **Sound-powered Technology:** Disruptive innovation opportunities to harness vibrations from sound to power different electronic devices. ### Sectors Adopting This - **Consumer Electronics:** Innovation in the consumer electronics industry by incorporating energy-generating sheets into a wide range of products. - **Smart Wearables:** Opportunity to integrate energy-generating sheets into wearable technology, such as smartwatches or fitness trackers. - **Sustainable Technology:** Incorporating eco-friendly elements into the production of energy-generating sheets for a more sustainable future. ## Related on Trend Hunter - [Efficient Energy Harvesting Tech](https://www.trendhunter.com/trends/efficient-energy-harvesting.md) - [Stretchable Sweat-Activated Yarn Batteries](https://www.trendhunter.com/trends/yarn-battery.md) - [Paper-Based Energy Storage](https://www.trendhunter.com/trends/paper-battery.md) - [Origami Travel Solar Panels](https://www.trendhunter.com/trends/solar-panel-origami-technology.md) - [Portable Energy Generators](https://www.trendhunter.com/trends/portable-energy-generator.md) - [Origami-Inspired Solar Panels](https://www.trendhunter.com/trends/sego-innovations.md) - [Ultra-Thin Stretchable Displays](https://www.trendhunter.com/trends/lg.md) - [Fluid-Filled Tactile OLED Screens](https://www.trendhunter.com/trends/flat-panel-haptics.md) - [Flexible Solar Film Energy](https://www.trendhunter.com/trends/heliafilm.md)
