Piezoelectric sensor

• A piezoelectric sensor is a device that uses the piezoelectric effect to measure pressure, acceleration, strain or force by converting them to an electrical signal. 
• Based on piezoelectric technology varous physical quantities can be measured; 
• The most common are pressure and acceleration. When the accelerometer experiences a motion, the invariant seismic mass loads the elements according to Newton’s second law of motion F = ma.
• Vibration sensors can also be used to harvest otherwise wasted energy from mechanical vibrations.

synesthesia territimely

Fantastic film! Synesthesia means that one stimulus stimulates other two or more senses. Not only does the film maker approach to daily objects from various perspectives, but also s/he re-presents one source as other sources metaphorically. The last half part which sound comes from speakers as the forms of objects reminds me considering to convey between invisible to visible senses or vice versa.

Paper prototyping

 From the paper prototyping, I'm considering to use more sensors and space efficiently. More than two sensors are needed both as a trigger and measuring 'variables' - reaction from audiences. Also, how to use a sphere or orb more flexible is considered. For example, setting mirrors or projecting could be possible rather than fill out the inside wall of the sphere with LEDs.

a motion sensor

Jon Sasaki, ‘Flyguy triggering his own motion sensor’ (2010)

A flyguy (one of the familiar dancing inflatables that wave people into carwashes and fast food restaurants) has been moved into the gallery and hooked up to a motion sensor.

2D Equations

The symbol is composed with following 4 equations.

* Wave - Ying and Yang

y1(x)= +sqrt(2^2-(x-2)^2)

y2(x)= -sqrt(2^2-(x+2)^2)

* Circle 
   x^2 + y^2 = r^2

   r = 4

y3(x)= +sqrt(4^2-x^2)

y4(x)= -sqrt(4^2-x^2)

Using LEDs

LEDs, which is stand for Light Emitting Diodes, are now very widely used in almost every area of electronics, mainly as indicator and display devices - in effect, 'solid state lamps'. They’re very well suited for this kind of use, because they are physically quite rugged and hence much more reliable than filament-type incandescent lamps.
They also run much cooler and are much more efficient, requiring far less electrical power input for the same amount of light output. Other common uses for LEDs are as a source of either visible or infra-red light, transmitted as a carrier for data and other information over short ‘line of sight’ distances. 

A LED is basically just a specialised type of P-N junction diode, made from a thin chip of fairly heavily doped semiconductor material. When it is forward biased to reduce the potential barrier provided by the junction’s narrow depletion layer, electrons from the semiconductor’s conduction band can combine with holes from the valence band, releasing sufficient energy to produce photons of light. Because the chip is thin a reasonable number of these photons can leave it and radiate away as its light output.

Project Essay

Intro
The Korean national flag is 'Tae-Geuk Gi', and 'Tae-Guek' means the symbol that is located in the middle of the flag. It implies the harmony of 'Eum-and-Yang,' which are representative of the heaven and the earth. Also, the harmony of 'Eum-and-Yang' reflects a creation theory of this universe in oriental theory. Simply, all things that are being in the universe are classified in two as in the beginning there were the heaven and the earth, male and female, and they attract each other under the law of universal gravitation.
To return to the symbol, simply, 'Tea-Geuk' consists of red and blue, and the wave sign is in between the two colors. If the symbol followed dualism or a black and white issue, the wave might be a straight-line instead of a curvy shape. Furthermore,
