Researchers from Dartmouth College and other institutions have developed a low-cost method to manage indoor Wi-Fi coverage using 3D-printed plastic shells wrapped in aluminum foil. This project, called WiPrint, uses software algorithms to simulate radio wave propagation based on specific floor plans, allowing users to redirect signals toward desired areas while minimizing leakage outside the home or into adjacent rooms.
* Increases signal strength by up to 6 decibels in targeted zones and reduces it by as much as 10 decibels in restricted areas.
* Provides a physical layer of privacy that complements digital encryption like WPA2 or WPA3.
* The complete setup is cost-effective, costing approximately $35 to build.

Researchers at MIT CSAIL have developed the Y-zipper, a three-sided fastener that enables objects to transition between flexible and rigid states. Inspired by a decades-old patent from Professor Bill Freeman, this new mechanism uses an automated software tool and 3D printing technology to create custom shape-shifting structures. The device can be used to quickly assemble camping gear, adjust medical wearables like wrist casts, or enable robots to change their limb dimensions for varied terrain.
* Three-sided triangular design for tunable stiffness
* Automated customization via software and 3D printing
* Rapid transition between soft and rigid states
* Versatile applications in robotics, medical gear, and outdoor equipment
