There are many information like ﬁeld, power spectra, linearity, distance, motor, and magnetic ﬁeld are described inside the paper. In this paper the reader can find info related to isometric force, power, control, output, metal, and channels.
This paper gives us explanation around force, noise, force sensor, panel, data, and sensor. Below are some excerpt from the paper:
In MEG studies, the motor system has been a primary focus of many research groups. Most of these studies involve active limb movements, especially ﬁnger and hand movements, to investigate corresponding activities in sensorimotor areas. By now, the movements themselves have been monitored by several means that can be classiﬁed in two categories: recordings of movement instances, i.e., speciﬁc points within the movement versus recordings of movement trajectories (e.g., velocity, force). Paradigmatic for the ﬁrst category are piezoelectric-crystal based sensors (Benzel et al., 1993) and optical switches (Xiang et al., 1997). Optical switches are commonly used because they produce the least artifacts and, in principle, allow for non-contact measurements.
Also, the paper contains information around spectra, isometric force production, strain gauge, frequency, noise levels, and methods.
