The E-tegel (EN: E-tile) is an innovative concept that uses piezoelectric material to convert vibrations from the (living) environment into energy. This way playing children can generate energy; by
jumping on the E-tegel they light up LED lights. This gives all kinds of possibilities for games.
Commissioned by Grijsen Park and Straat Design in Winterswijk, Prange BV develops the electronics for the E-tegel, the assembling of the tile is performed by Prange as well.
