5. E-TEXTILES & WEARABLES I#

In my intempt to aproach to the lingerie design I imagine a bra which reacts to the pressure of a hand.

Pressure Sensor#

The material used was:

Velostat Conductive thread Insolation material (fabric sponge in this case) Led

Velostat is a resistive material made from carbon impregnated black polyethylene, it has a volume resistivity of <500 Ohms/ cm. By pressing the Velostat it allows more electricity flow through and this is how we get the led turned on.

Arduino + Flora#

Flora#

The board used to program the led´s function is called Flora in the scheme bellow you can see the connections. Here you can get more information about Flora

RGB Circuit#

To make a RGB work, you need resistors and conect 3 of the legs to a different pin each and the largest one to Ground. You can follow the scheme bellow.

Simple loop program#

It is very simple to program a simple loop program haha

  1. Download Arduino Program or use it online here
  2. You can find some libraries previously programed in File>Examples and follow the instructions in gray letters

Bend sensor program#

Capacitive Sensor#

The capacitiveSensor sense the electrical capacitance of the human body. All the sensor setup requires is a medium to high value resistor and a piece of wire and a small (to large) piece of aluminum foil on the end. At its most sensitive, the sensor will start to sense a hand or body inches away from the sensor. Capacitive sensing may be used in any place where low to no force human touch sensing is desirable.

A capacitive sensor covered with paper or other insulator also acts as fairly good (human touch) pressure sensor with an approximately logarithmic response
