Summary

The authors propose a toolkit enabling the creation of sensors, input widgets, and interactive objects that can communicate with smartphones and Wi-Fi devices.

Key Innovations:

1. Printed Wi-Fi: The first 3D-printed design capable of transmitting data to commercial RF receivers using Wi-Fi backscatter technology. This leverages plastic filaments with conductive properties and gears to encode bits, creating a fully printable backscatter switch.

2. Printed MagLink: A method for embedding static data within objects using magnetic fields. Information like object attributes or creator details can be encoded without altering the physical appearance.

Applications:

- Sensors: 3D-printed weight scales, flow sensors, and anemometers that transmit data wirelessly.
- Interactive Objects: Eyeglass frames, armbands, and artistic models with embedded magnetic data.
- Control Devices: Buttons, sliders, and knobs for controlling music volume and lights, all operating wirelessly.
- Smart Bottles: Capable of sensing liquid flow and sending data to nearby devices.

Advantages:

- Democratizes ubiquitous connectivity by enabling designers to create wireless objects without specialized engineering knowledge.
- Allows customization and tailored functionality through 3D printing.
- Potential for self-monitoring and ordering in inventory management systems.

Description

Students from the University of Washington present a toolkit enabling 3D printed objects to communicate wirelessly with smartphones via Wi-Fi or magnetic fields, eliminating the need for batteries or internal electronics. This novel approach integrates wireless connectivity into 3D digital models using commodity printers and plastic filaments.
