5. Solder a thin wire (approx. 50 cm) on the top of the brick which will be con-

nected later to ground.

USAGE OF THE HAND BRICK AS ARTIFICIAL HAND

For parameterization and performance evaluation purposes of the customer’s

electrode design, the kit contains a set of hand and spacer bricks. This artificial hand

brick simulates Human Hand effect and is made of a Styrofoam block covered with light

copper and has a fixed size. Spacer bricks (Styrofoam block without copper layer) are

used to position the hand brick in different heights to the electrode. Because of a εr≈1of

Styrofoam, the spacer brick does not influence the measurement results.

For quick parameterization, the ground wire connected to the hand brick should be

maintained using your hand which emulates the ground connection. The wire should

be hold at 50 cm minimum and the line should also be straight to avoid any influence

to the system sensitivity as shown in Figure C-1.

For parameterization process, please refer to “MGC3130 GestIC® Design Guide” and

the appropriate wizards in Aurea PC software.

Thin wire for grounding (e.g.

0,15mm diameter, 50cm length)
