# Smart Hand Prosthetics The Handiii 3D Printed Bionic Arm Uses a Smartphone to Control Movement By Alyson Wyers | Published 2015-04-10 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/3d-printed-bionic-arm References: [springwise](http://www.springwise.com/usd-300-myoelectric-hand-controlled-electronically-nerves/) & [exiii.jp](http://exiii.jp/eng.html) This 3D printed bionic arm is also a smart one, so it connects to the wearer's smartphone. Developed by Japanese company Exiii, Handiii enables users to control the [myoelectric hand](https://www.trendhunter.com/trends/the-nimble) with their nerves and muscles. Handiii acts as a more affordable alternative to the expensive and homogeneous prosthetics at $300 USD. A regular prosthetic hand is hard to customize, let alone repair. The Handiii, however, uses an [EMG sensor](https://www.trendhunter.com/trends/meta-emg-wristband) to read electric signals from the wearer's movements. Smartphones can then translate muscle signals into arm motions, allowing the user to control the device more naturally and instinctively. The 3D printed bionic arm is able to be printed in a wide range of colors and is easily produced and replaced if necessary. ## Trend Insights (Trend Hunter) - Score: 3.4/10 - Popularity: 66% | Activity: 29% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [AI](https://www.trendhunter.com/ai) ## Key Themes ### Key Themes Behind This Trend - **Smart Hand Prosthetics:** Disruptive Innovation Opportunity: Develop affordable and customizable prosthetic solutions using smart technology. - **Myoelectric Control:** Disruptive Innovation Opportunity: Explore the use of EMG sensors and smartphones to enhance intuitive control of prosthetic limbs. - **3D Printing in Prosthetics:** Disruptive Innovation Opportunity: Utilize 3D printing technology to create cost-effective, customizable, and easily replaceable prosthetic arms. ### Where This Applies - **Medical Devices:** Disruptive Innovation Opportunity: Improve and revolutionize the field of prosthetic devices with smart, myoelectric-controlled options. - **Biotechnology:** Disruptive Innovation Opportunity: Merge biotechnology with prosthetics to create advanced and personalized solutions for individuals with limb loss. - **Additive Manufacturing:** Disruptive Innovation Opportunity: Apply 3D printing technology in the production of prosthetic arms for enhanced customization and accessibility. ## Related on Trend Hunter - [Smart Bionic Hands](https://www.trendhunter.com/trends/smart-bionic-hand.md) - [Affordable 3D-Printed Prosthetics](https://www.trendhunter.com/trends/lunet.md) - [App-Customized Arm Braces](https://www.trendhunter.com/trends/appcustomized-arm-braces-the-brace-elbow-brace-by-nils-sorger-is-3d-printed.md) - [Mind-Controlled Artificial Arms](https://www.trendhunter.com/trends/ai-prosthetic-arm.md) - [Enhanced Thumb Prosthetics](https://www.trendhunter.com/trends/third-thumb.md) - [Bionic Knee Prostheses](https://www.trendhunter.com/trends/httpswwwmediamitedu.md) - [Robotic Hand Assistance Solutions](https://www.trendhunter.com/trends/bioservo-carbonhand.md) - [Open-Source Robotic Arms](https://www.trendhunter.com/trends/bus-servo-robotic-arm.md) - [Lightweight Robotic Hand Designs](https://www.trendhunter.com/trends/robotic-hand1.md)
