The resulting chitosan IBMCs have been
manufactured in various shapes and forms for a
number of medical applications in connection
with bodily fluid drainage problems such as in
hydrocephalus, as shown in
Figure 6.5
.
A number of tests were performed on the
new chitosan IBMCs in terms of actuation,
sensing, and force exertion. Essentially the tests
employed various samples of IBMCs, as shown
in
Figure 6.5
, in a cantilever form between two
electrodes at one end. A dynamic voltage
generator was used to generate low voltage
(4-6 V) and transient current (
∼
100 mA s). For
actuation purposes, the IBMCs were subjected
to low voltage and current to study their bending
deformations, as shown in
Figures 6.6
a-d.
