Innovative 3D-Printed Plate Pioneers Computational Food: Electrifying Dining Experience

Imagine a dining experience where food droplets come to life, choreographed like dancers on your plate. This is precisely what the "Dancing Delicacies" computational food project aims to achieve. Collaborating across borders, scientists from Monash University’s Exertion Games Lab, Carnegie Mellon University’s Morphing Matter Lab, and Gaudi Labs in Switzerland have brought this vision to life. Their groundbreaking invention is a 3D-printed plate that employs electrical voltage to manipulate liquid droplets.

"Cooking and eating is more than simply producing a dish and then facilitating energy intake," explains co-author Floyd Mueller of Monash. "It is about sharing, caring, crafting, slowing down and self-expression, and Dancing Delicacies aims to highlight these virtues at a time when they are often forgotten. The integration of food and computing will transform how we understand both computing and food as not two very different things, but a new frontier that combines the best of both."

This project draws inspiration from molecular gastronomy and molecular mixology, where chefs have already delved into the realm of food innovation. For instance, creating desserts that bloom like flowers when exposed to hot chocolate sauce or cocktails that change color based on their pH levels. On the technological front, MIT's Media Matters Lab experimented with shape-changing forks and LED-equipped utensils to enhance the dining experience.

Building upon these innovations, the CMU Morphing Matter Lab introduced pasta that transforms into specific 3D shapes when cooked. They also experimented with edible 2D-layered films that morph into 3D shapes as they absorb water. Monash's Exertion Games Lab explored food as a "computational artifact" with interactive cups and edible logic gates.

The latest approach by Deng et al. takes it a step further. By using electrowetting on dielectric (EWOD) technology, typically used for manipulating liquid droplets in various applications, they've allowed food items to dynamically respond to external stimuli. Liquids such as soup, broth, coulis, liquor, and syrup can be manipulated and choreographed on the plate, offering diners the ability to reconfigure their meals.

To make this vision a reality, custom 3D-printed plates were designed with an electrode board array, dielectric film, and an insulating layer to separate electronics from the food. "Yin & Yang" and "A Taste Ballet" are just two examples of how this technology can be applied, showcasing black and white sauces in opposing patterns and different flavored droplets moving around the plate.

The possibilities are endless. From instructional dishes like "Jelly Wagashi" to performative experiences such as "Seasonal Transience," this innovative approach opens doors to redefine the way we interact with food. It even allows for directional choices in dishes like the "Meta Platter."

While this technology is currently limited to liquid foods, it offers a glimpse into a future where we can perform precise "micro-cooking" on our plates. As the boundaries between food and technology continue to blur, the "Dancing Delicacies" project offers a tantalizing glimpse into what the future of dining could look like.
