The discourse surrounding intangible materials in interaction design is often directed toward computational materials [2, 9], however, this studio focuses on sonic and electromagnetic fields as intangible materials with distinctive qualities and methods of interaction. Participants explore the notion of extended body by augmenting their natural hearing abilities through body-space-object interactions. Using analog and radio-frequency (RF) sonic extenders, participants direct, block, amplify, and filter sounds, and perceive the surrounding electromagnetic landscape, thereby creating a "super sense" of heightened audition. This sonic experience explores the sensorial possibilities of the future body, where aural augmentation could take place. Using soundwalking and soundmapping as methods, participants explore transitive sonic forms that change their qualities and content over time in downtown Sydney. Participants produce a collective soundmap identifying embodied sonic extensions and acousmatic techniques, along with movements, gestures, and choreographies. This data will be used to stimulate a final discussion.

“…The antenna, later on, is packaged with a porous polyurethane web as an additional process to make the antenna durable, breathable, and water repellent, which is an additional, delicate and expensive step to avoid the effect of humidity over the textile antenna. Previous literature on wearable textile antennas so far has been limited to a number of discrete properties like dual-band antenna [ 21 , 22 , 23 , 24 ], bending effect on the resonance frequency of the antenna [ 25 , 26 ], usage of novel conductive electrotextile fabrics to construct textile patch antennas [ 27 ], and comparison of different textile properties [ 28 ]. Another important aspect is the physical performance of the wearer of a textile antenna, which can be affected if a textile antenna, despite its relatively small size, resists the transportation of humidity and/or perspiration and remain trapped inside a textile antenna can be uncomfortable even to a little extent for the wearer.…”

A textile patch antenna is an attractive package for wearable applications as it offers flexibility, less weight, easy integration into the garment and better comfort to the wearer. When it comes to wearability, above all, comfort comes ahead of the rest of the properties. The air permeability and the water vapor permeability of textiles are linked to the thermophysiological comfort of the wearer as they help to improve the breathability of textiles. This paper includes the construction of a breathable textile rectangular ring microstrip patch antenna with improved water vapor permeability. A selection of high air permeable conductive fabrics and 3-dimensional knitted spacer dielectric substrates was made to ensure better water vapor permeability of the breathable textile rectangular ring microstrip patch antenna. To further improve the water vapor permeability of the breathable textile rectangular ring microstrip patch antenna, a novel approach of inserting a large number of small-sized holes of 1 mm diameter in the conductive layers (the patch and the ground plane) of the antenna was adopted. Besides this, the insertion of a large number of small-sized holes improved the flexibility of the rectangular ring microstrip patch antenna. The result was a breathable perforated (with small-sized holes) textile rectangular ring microstrip patch antenna with the water vapor permeability as high as 5296.70 g/m2 per day, an air permeability as high as 510 mm/s, and with radiation gains being 4.2 dBi and 5.4 dBi in the E-plane and H-plane, respectively. The antenna was designed to resonate for the Industrial, Scientific and Medical band at a specific 2.45 GHz frequency.
