Materials and Method
Calculation of the torque to raise up the finger
If L=9cm and D=1.4cm
T orque[N m] = F orce ∗ L
Force [N] = m*9,81
(1.1)
With the assumption that the human body has the same weight than the water :
m [Kg] =Vf inger ∗ 1000
Vf inger = π ∗ r2 ∗ L = π(0.007)2 ∗ 0.09 = 1, 385 ∗ 10−5 m3
so m = 0, 014 [kg]
Force= 0.136 [N]
Torque= 0.0122 [Nm] (1.2)
Figure 1.1: Motor torque
As the body is not composed of only water and to avoid the effects of muscle movement, the minimum torque
was set at 0.122 [Nm].

CHAPTER 1. APPENDIX
Calculation of the resolution
A previous search indicates that during a tapping motion at a frequency of 1.25Hz, the flexion time corresponds to
0.1s and the extension time corresponds to 0.2s. So if the record is 1000Hz, the minimum resolution equal:
30
resolution =
=0.15 degree
0.2 ∗ 1000
