The apply of electric paint(take paper bend sensor as an example)

These days, I found a very interesting material: the electric paint. To be more specific,this Paint is one kind of water-based paint but that it’s electrically conductive, which means that you can actually paint wires onto things like models, clothes, furniture, walls and so on.

Due to people can use this paint to replace ordinary wires, so there are many creative products appear. For instance, by combining conductive ink and paper creases, Alice Rzezonka made her first paper bend sensor. Specifically, placing creases on top of a line of conductive ink folding the paper changes the resistance of electricity flowing through the ink.

Materials:Japanese Spatula, electric paint, paper or cardboard (around 250g/m²), masking tape, bone folder, clear spray paint, ruler, resistors 10k Ohm, arduino board,  jump wires, alligatorclips,  breadboard.

Make:

1) To make the stripe of conductive ink cover the parts of the paper that you don’t want to paint with masking tape. There is special masking tape for paper, if you don’t have that stick the tape on and off a clean surface until it is not too sticky anymore and won’t damage the paper.

step1

2) Now use the spatula to spread the paint evenly. Take the masking tape off while the paint is still wet, this will get you clean etches.

3)Once it is dry cover everything with clear spray paint to seal the conductive ink and prevent it from smudging.

step2

4) With the help of the ruler and the bone folder create creases on top of the painted stripe. With the layout of the creases you actually determine how the resistance along the stripe will change when bended. Creating multiple creases will lead to a wider range of resistance change and react to folding different parts of the stripe. How strong you fold the paper along the creases also makes a strong difference. At this point I recommend experimenting with the different parameters until you get a feeling for it.

Code:

/*
based on the AnalogReadSerial example
Reads an analog input on pin 0, prints the result to the serial monitor.
add averaging of the values:
Define the number of samples to keep track of.  The higher the number,
the more the readings will be smoothed, but the slower the output will
respond to the input.
*/
int inputPin = A0;
int sensorValue = 0;        // value read from inputPin

const int numReadings = 25;
int readings[numReadings];      // the readings from the analog input
int index = 0;                  // the index of the current reading
int total = 0;                  // the running total
int average = 0;                // the average

// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
/*____ read & smooth values ____*/
// subtract the last reading:
total= total – readings[index];
// read from the sensor:
readings[index] = analogRead(inputPin);
// add the reading to the total:
total= total + readings[index];
// advance to the next position in the array:
index = index + 1;

// if we’re at the end of the array…
if (index >= numReadings)
// …wrap around to the beginning:
index = 0;

// calculate the average:
average = total / numReadings;
// send it to the computer as ASCII digits
// read the analog in value:
sensorValue = average;
// print out the value you read:
Serial.println(sensorValue);
delay(1);        // delay in between reads for stability

What inspired me:

This kind of paint may can help me expand the type of my sensors in Music Garden.Not only by pass the pots/flowers,but also by touch/bend or even more ways.

REVIEW OF ETHNOGRAPHY

Ethnography is the systematic study of people and cultures. It is designed to explore cultural phenomena where the researcher observes society from the point of view of the subject of the study. As for the methods for Ethnography, fieldwork is no doubt a main way for researchers to get various data and materials about society.

Specifically, fieldwork is the collection of information outside of a laboratory, library or workplace setting. The approaches and methods used in field research vary across disciplines. For example, biologists who conduct field research may simply observe animals interacting with their environments, whereas social scientists conducting field research may interview or observe people in their natural environments to learn their languages, folklore, and social structures. For instance, by observing or interviewing people, social scientist can obtain knowledge about their languages, social relationship, habit and so on.

Field research involves a range of well-defined, although variable, methods: informal interviews, direct observation, participation in the life of the group, collective discussions, analyses of personal documents produced within the group, self-analysis, results from activities undertaken off- or on-line, and life-histories.

As for creative art part, ethnography has some new features, including naturally occurring settings(How do artists work, how do audience work),ordinary activities(observe people from daily and natural life),Social meanings(how do people create and find meaning),The how of the social organisation of activities(eg. accident report), The perspective of the paticipants(in my opinion, it’s the aspect to change perspective to observe),The member categories(what is your TA, if you want to get more precise data, you need to expand the social groups),Descriptive(Say what you saw and reflect on the theory),Participant observation(you should be both participant and observer), Reflexivity (Reflexivity refers to circular relationships between cause and effect,In sociology, reflexivity therefore comes to mean an act of self-reference ).

Activities: 1 Observe what kind of art works people may interest in Northumberland street

2 make a proposal for public artworks

Outcomes:

Observe part(Thursday, 11AM)

People walk quickly on the street

Most of them are old people (couples, with shopping bags) and students (without shopping bags, just passing the street).

People prefer indoor activities.

People will cast a glance at sculpture in the street.

Artwork proposal

1. Small art market in the center of the street.

2. Small LED door in the center of the street, people can open the door and connected the people from other place or even different ages.

Aim: to attract people to participant in more outdoor activities .

 

To sum up, by the way of  ethnography, artists need spend a lot of time to observe and experience their target audience, only in this way, artists can get enough data and make a comprehensive plan for their works.
