exhibition in helsinki _ Prima Materia; art & science

Recommended to check out this exhibition:

Prima Materia

Location: Tiedekulma – Aleksanterinkatu 7, Helsinki.
Duration 22. November – 13. December

Laura has there 2 wearable works; A Unit (2 prototype versions) and Evidence. They take the starting point in science research that investigates human health and its relation to green areas. (more in the venue at Tiedekulma / Helsingin Yliopisto… (and later on more on her website)).

Heart beats Pendulum

HBP is a wearable technology project inspired in Rafael Lozano- Hemmer Pulse Room. It attempts to use a portable heart beat sensor (embedded in a pulse clock) in order to control a pendulum oscillator. As follows, it strives to perform the most accurate heart rate measurement in order to modify oscillator behaviour.

Consequently i found a clear introspection related to control and routines of a pendulum.

Upcoming challenges:

-Mapping heartbeat

-Embedding sensors in a discreet manner

Color Ring

Color Ring is a unique light ring that allows the wearer to interact with the surroundings by color sensing technology. People can customize the ring by collecting the color they like from any object by simply touching it. The color will be stored into the ring and then displayed out. It aims to create a special experience by bringing more personal emotions into the interactive process.

• Hardware

LilyPad Simple Board, Sparkfun HDJD-S822 Color Sensor, RGB LED, Pushbutton, Conductive Thread, Polymer Lithium Ion Battery (3.7V)

• Other Materials

Armwarmer, Ring Base, 3D Printed Cover

DIY Electrodes

Hello, I found this to do one’s own electrodes. Doesn’t seem too complicated!

The electrodes

Coax plug
Coax wire connectors Sponge ear plugThe electrodes are made from coax connectors and ear plugs (sponge).

The pin assembly inside the plug is removable and is clamped onto the end of the cable with a screw.

The pin is inserted into a hole in the back of the sponge. You can use something like a bamboo skewer to prepare the hole.

The sponge is pre-soaked for at least a day in a saline solution.

I also use one of these for my DRL (driven right leg).

Cello & shirt-sensors; real-time manipulation

A video showing Peter Gregson rehearsing for a demo at the TEI conference at MIT. He is wearing a shirt fitted with custom designed stretch sensors designed by Sarah Kettley and Martha Glazzard. These sensors are sending data to custom software designed by Yann Seznec in Max/MSP which manipulates the sound of the cello in real time.
