Gesture control
Enables an automated grip to be accessed through a
smooth motion of the prosthesis in one of four directions
(forward, back, left or right). The grips programmed for
each direction are customized to the users requirements
using the biosim®and my i-limb®app.
To access gesture control:
• Hold i-limb®hand parallel to the ground (elbow
bent to 90°)
• Maintain an open signal until index finger twitches
• Move the i-limb® hand (within 1 second) in direc-
tion assigned to the desired grip
• The i-limb® hand will adopt the grip
• To exit the grip hold an open signal until the hand
exits the grip
Default setting for gesture control is hold open, however
it can alternatively be accessed using cocontraction. This
is changed using the biosim®and my i-limb®app.
App control
An automated grip can be accessed at the touch of an
icon on the biosim®and my i-limb®app. These are called
quick grips®. The i-limb®hand will exit the grip when the
icon is tapped again or by selecting another grip icon to
enter.
Speed boost is also available on the app using a simple
slider bar. The increase in speed of the digits oers a
more responsive action, more natural appearance and
increased grip force potential.
Muscle control
Triggers are specific muscle signals that can be used to
access an automated grip. There are 4 potential muscle
triggers: hold open, double impulse, triple impulse and
co-contraction.
Proximity control
Grip chips®are small Bluetooth®chips which can
change the programming of the i-limb®hand when you
position the hand near to the chip. The grip chips®can
be positioned in practical locations to allow access to the
optimum grip for particular tasks at that location. The in-
dividual grip chips®are programmed using the biosim®
or my i-limb®app and can be reprogrammed by the user
at any time as required.
For further information on grip chip use and set up refer
to i-limb hand user manual (MA01382).

2.0 Prosthesis fabrication
The i-limb hand is assembled in combination with a
socket made to the requirements of the individual user.
When fabricating the prosthesis for the i-limb®hand
consideration should be given to:
a. Electrode positioning
b. Battery placement, size and configuration
c. Charge port placement
d. Socket length and overall length of the prosthesis
Precautions should be taken against sweat entering the
components, as sweat ingress can cause damage and
compromise the function of the prosthesis.
The use of carbon fiber is not recom-
mended due to electrical conductivity.
2.1 Socket materials
The socket design and materials used for the prosthesis
are based on the clients presentation and skin condition.
Typical inner socket materials include silicone, thermo-
plastic and laminate. The outer socket is primarily lami-
nate.
For a standard prosthesis, a minimum expected layup
would be;
Inner socket: 2 layers of perlon stockinette, 2 layers of
nyglass and 2 layers of perlon stockinette.
Outer socket: 4 layers of nyglass and 2 layers of perlon
stockinette.
The build of each prosthesis should be adjusted specifi-
cally to meet the individuals requirements.
It is not recommended to use carbon fiber within a myo-
electric prosthesis.

8 of 27 9 of 27
2.2 Electrodes
When myotesting it is advisable to use the same elec-
trode type as will be used in the users definitive pros-
thesis.
The electrode should be fitted into the socket in the op-
timum position identified during myotesting. The elec-
trode must remain in contact with the skin throughout
the users range of motion, during use of the prosthesis.
Loss of contact between the skin and the electrode re-
sults in poor control of the prosthesis.
It is recommended not to set the electrode gains higher
than ‘5’.
Compact electrodes
When assembling, the electrode cable must be cut
straight and fully inserted into the IDC block to ensure
proper contact is achieved. The grey side of the cable
must be facing the outside.
Remote electrodes
When assembling the remote electrode the order of
parts should be: electrode dome, socket interface, shake
proof washer, eyelet, nut.
The middle cable on the electrode is the earth/ground
cable, it should be secured to the dome positioned be-
tween the other 2 domes.
Optimum remote electrode domes spacing is 8-10mm
from center to center.
The domes must not be touching.
Fig. 11: Remote electrodes
Fig. 12: Remote electrode dome
Fig. 10: Compact electrodes
Avoid dirt or fluids coming in contact
with the electrode.
Regularly clean the electrode contact sur-
face with mild soap and a damp cloth.
The electrode is an applied part.

Fig. 14: Powerpack batteries
2.3 Batteries
Touch Bionics batteries, magnetic charge port, DC port
or switch block components should always be used with
the i-limb®hand. The battery should be changed every
12 months.
Only Touch Bionics batteries are ap-
proved for use with the i-limb®hand. Use
of alternative batteries will invalidate the
warranty and compromise general safety
of the device.
Cutting or modifying the battery wires in
any way will invalidate the warranty and
compromise device safety.
Internal batteries
Internal batteries are available in 1300mAh or 2000mAh.
The internal battery is designed to be positioned be-
tween the inner and outer socket. Ensure adequate space
is created during fabrication of the prosthesis by using
the battery dummies.
It is advisable to create a flat surface within the outer
socket for the battery to be attached to the surface using
Velcro.
Powerpack batteries
Powerpack, external, batteries have a housing mounted
on the outer surface of the prosthesis. Standard fabrica-
tion processes and techniques should be followed, utiliz-
ing the housing dummies to create the necessary shap-
ing to accommodate the battery housing.
Do not bend or shape the battery in any
way.
Ensure the battery is not subject to contin-
ued pressure once fitted.
Do not handle the battery by the wires, or
pull on the wires

2.4 Magnetic charge port
It is important to provide sucient space for the charge
port between the inner and outer sockets.
When fabricating the outer socket the magnetic charger
fabrication dummy should be used. The dummy is in 3
parts:
Dummy 1: is the thickest dummy. It is used to ensure
sucient clearance within the outer socket/frame for the
magnetic charger port.
Dummy 2: has the central hole. It creates the step to re-
cess the magnetic charge port.
Dummy 3: is the ring. It is used after lamination to create
the necessary hole.
1. Position the dummies in
desired location during prepara-
tion for final lamination, dummy
1 should be recessed within the
outer socket/frame build down.
2. Position dummy 2 prior to ap-
plying final two fabric layers.
Laminate as normal.
3. Once laminated, grind surface
to expose dummy 2.
Drill through central hole of
dummy 2.
4. Remove dummy 2 and insert
dummy 3.
5. Grind lamination to create hole.
Remove dummy 3.
6. Insert magnetic charge port
securing in position with silicone
adhesive.

tion until it disengages
2. The hand will disengage from the prosthesis

12 of 27 13 of 27
3.2 Wrist disarticulation assembly
During fabrication consideration should be given to cre-
ate sucient space for the wiring and switch block and
battery location.
The lamination plate is fabricated directly into the outer
socket. No rotation is possible at the wrist and therefore
the fixed positioned should be set to be optimal for the
user.
To connect the i-limb®hand to the lamination plate,
1. Remove the palmar fairing of the hand using a T10
screwdriver
2. Feed the power cable through the hole in the plate
3. Align the slots and slide the hand onto the plate
4. Screw the hand and plate together using a T10 screw
5. Replace the palmar fairing, ensuring not to pinch the
wiring
To remove the i-limb®hand from the lamination plate,
complete the steps in reverse.

nate and then turn o.
To check battery level
The power remaining in the battery can be checked by
observing the bars when the power is on.
Each bar of light indicates 20% charge. The number of
bars lit up will indicate the percentage of power remain-
ing in the battery.
A red low battery warning light will indicate when 5 % of
the battery remains. The light will remain lit for 3 min-
utes and then the prosthesis will power o.
