Metamaterial Mechanisms – 3D Grids with Mechanical Properties

Category Members News ObjectsPosted on:

Metamaterials are engineered 3D cell grids that have properties that are not found in nature. Recently, a group of Hasso-Plattner Institute researchers (supported by a Shapeways educational grant) enhanced metamaterial design to include mechanical functionality – the cell grids are designed with motion, shear and compressive forces in mind to accomodate specific functions (e.g. a door latch with one part/composite assembly).

We push the concept of metamaterials further by creating objects that allow for controlled directional movement. This allows users to create objects that perform mechanical functions. Our objects thereby implement devices that transform input forces and movement into a desired set of output forces and movement—also known as mechanisms. We demonstrate metamaterial objects that perform a mechanical function. Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch.

Markov Decisions – Sound as a physical property of matter

Created by Matteo Crivella, Markov Decisions is a generative audio system that combines random processes and sonic behaviours of matter. Data is created in Pure Data that drives the instrument through voice coil actuators putting the sheet of brass under stress and generating a tensional field in which the metal changes from one vibrating state to another, in relations to the input and its physical properties (mass, elasticity, morphology).

Call for Researchers to join Antikythera

Applications are now open for Antikythera’s Studio, which will host 15-18 international, interdisciplinary Studio Researchers from February to June 2023. The program is free and includes a housing provision and a monthly stipend of 4000 USD (or equivalent when not in Los Angeles). All travel and other associated program costs will also be covered by the program.
