This project pretends to be part of an on-working and collaborative performance that involves dance theory, embodiment and technology. It holds the idea of thinking the body as a device and you can read a summary about it in my final project page. Also you can read the whole background in [no dispositivo]'s website, the previous work that I made during 2014.
It will be a tool for the performative arts field. It will be a modular body sensor system that will take movement data from several parts of the human body and will send it to a computer. This project explores the possibilites to design sensors made of fabric and it's applications to outputs such as sound, robotics, ligths, visual arts, etc.
I pretend to design several sensors (or at least one ) using conductive fabrics, such as: capacitance sensors in the back, bend sensors in articulations, preassure sensors and possibly stretch sensors.
//OBJECTIVES
I will use conductive thread, velostat, conductive stretch fabric to create sensors. Based on the experimentation I made during the "Networking and communication" input devices week.
Neoprene or similar fabric to create wearables.
Radio communication modules. nrf24L01+ module, based on my "Networking and communication" assignment week.
ATMEGA 32u4 and possibly ATtiny88. It will depend on the size of the libraries I'll need to use to code and program.
Filaflex or acrylic depending on the size of the final PCB.
3 Axis ADXL343BCCZ-ND accelerometer chip, to be included in final PCB.
Conductive fabrics: I already bought them several weeks ago through the website "PLUG AND WEAR". The shipping was super expensive so I took
Radio Modules were bought via AMAZON as there weren't available in the lab.
If you are interested on buying this kind of materials, here I share a list of companies dedicated to produce and or commercialize them:
Everything else is in the lab. :)
By this week I already had some important components bought.
I also decided to use the ATMEGA32U4, because it had the enough size for the libraries of the radio communications and I already knew how to program it.
I based the calculations of the prize looking at provider's websites. This is pretty much a real aproximation of the material's costs of my final project.

- Modular PCB with special holes for sewing conductive thread.
- Textile modules that will contain PCB's
- Cases for PCB's
Week1= Read and choose between ATMega32U4 or Attiny88. Design by hand all of the components. Keep on reading and experimenting with different libraries for radio modules. Design PCB including battery, nrf24l01, and space to connect more than one sensor.
Week2= Mill and solder PCB, code. If everything went well, make 2nd PCB. Design and produce textile modules: ARM MODULE, VEST MODULE, KNEE MODULE, ETC. ( At least one of them !)
Week3= Programming, testing, experimenting. Documentation.
I will use it myself and let other people also use it while I receive data in the computer.
I would like to make some tests with electroacoustic music composers and interpreters.
I would also like to work with a dancer, receiving her movement data.
