Smart and modern materials

Each pixel point cotains black beads (negativly charged) and White beads (positively charged). Each pit is topped with a tranaperent electrode and has two other electrodes at its base. Altering the charge on the base electrodes makes either the white or black beads leap to the top. forming either a blank or black spot on the larger display, Mkaing one base electrode positive and the other negative creates a grey spot. 

The transmitter sends signals to the transponder: The transponder then transmits a resonse signal that is recieived by the transmitter. The information from the transmitter can be used to identify the transponder and any item it is attached too. 

Senses heat from the body 

Coductive ink > forhead  >Tempreture gauge colour bars > Thermochromic layer. By presssing the thermomoter to the forhead, the tempreture generated turns the thermochromic ink translucent. This reveals the tempreture generated turns the thermochric ink translucent.  

A piezoelectric crystal is a material that expands and contracts when electric current is applied. The piezoelectric effect converts this mechanical stress or vibration into electrical signals and vice versa. 

A cell containing a liquid crystal has a voltage applied, and on which it appears to to go 'dark'. This caused by the molecular rearrangement within the liquid cystal. The LCD has a pattern of conducting electrodes that is capable of displaying numbers via 7 segments. These are then made to appear by applying voltage to the different segments, which turn dark in relation to the silvered backround. 

Absorb energy during the daytime conditions and are capable of storing that energy for some time, then releasing it relatively slowly in the form of light. 

Electrolimiinescient lighting converts electrical energy into light energy by applying a voltage across electrodes- 

An organic phosphor is sandwhiched between two conductors and the electric current is applied. The charged phosphor crystals emit readiation in the form of visable light.
