) Relationship between lower/upper bounds on pin-counts and the sizes of the
electrode array (rectangular layouts) for biochips with 2
droplets; (
b
) relationship between
lower/upper bounds on pin-counts and the sizes of the electrode array (outlined rectangular layouts)
for biochips with 2
droplets
For an n
n array, the lower bound and upper bound for the number of control
pins are shown in Fig.
6.11
a. For an n
n outlined rectangular array, the lower
bound and the upper bound for the number of control pins are shown in Fig.
6.11
b.
By comparing the lower/upper bounds on the number of control pins presented in
Fig.
6.8
and
6.11
, we can find that the number of pins assigned to the biochip has to
increase in order to manipulate 2
droplets.

Influence of Diagonal Electrodes
In this subsection, we discuss the influence of diagonally adjacent electrodes on the
movement of a droplet. Assume that the droplet shown in Fig.
6.12
a will be moved
in the direction of the arrow, and the electrode that the droplet will be moved to is
actuated. The contact line between the droplet and the actuated electrode is shown
