Each custom built module consists of an electroluminescent light wire linked to a piezoelectric sensor and a microcontroller. Through its modular setup it can easily be adapted to various urban spaces. The sensors are used to measure vibrations of architectural solids in a range of low frequencies. These oscillations are triggered by surrounding ambient noise, for example traffic noise. The sensor data controls the light wires, which are tensed to a spatial net structure. According to the values of the measurement light flashes are generated. With increasing vibrations the time between flashes becomes shorter and shorter. The stability of this nervous system gets to an end where it collapses and restarts again. A dynamic light space is thereby created, which creates a visual feedback of the aural activity around the installation.

hardware / software
The microcontroller of each module is based on the physical computing platform Arduino and was custom built for this project. Each module has its own simple program logic and there is no digital connection between the elements. Their behavior is triggered by the aural conditions of the environment.

Abstract:
A instalação “corpo capacitivo” é um sistema de luz modular que reage aos sons do ambiente. Cada módulo feito sob medida consiste em um fio de luz eletro-luminescente ligado a um sensor piezelétrico e um microcontrolador. Através desse esquema modular ele pode ser facilmente adaptado a diversos espaços urbanos. Os sensores são utilizados para medir as vibrações de sólidos arquitetônicos em uma faixa de baixas frequências. Essas oscilações são provocadas pelo ruído ambiente, por exemplo, o ruído do tráfego. O sensor de dados controla os fios de luz, que são estendidos em uma estrutura de rede espacial. Conforme os valores da medição, são gerados flashes de luz. Com o aumento das vibrações, o tempo entre os flashes torna-se cada vez menor. A estabilidade desse sistema nervoso chega ao fim quando ele desmorona e recomeça. Um espaço de luz dinâmica é assim criado, gerando um feedback visual da atividade aural ao redor da instalação.

His focus is on reactive installations with the limits of human perception. The questioning of the credibility of mediated content and the blurring of boundaries between reality and virtuality. His work has been shown in many institutes and international festivals of media art.
