The basic required
technologies seem to be maturing and a drastic cost reduction period started.
The cofiring technology provided a dramatic reduction of the manufacturing cost of the printer head, in addition to the performance improvement; that is, the unnecessary vibration of the ink chamber was suppressed.
Figure 9 shows the current best data reported by Toyota Central Research Lab, where strain curves for oriented and unoriented (K,Na,Li) (Nb,Ta,Sb)O3 ceramics are shown [8].

As a higher strength of AAC is reached because of the reduction of the water to binder ratio, also fatigue parameters start to get more and more importance.
Because of this, the data obtained from the fatigue tests were normalized to a specimen age of 28 days.
According to equation (3), the power function and coefficient of determination for Material 1 obtained directly from measured data are the following: (4) and for data normalized to a specimen age of 28 days: (5) Material 2 has following parameters of Wöhler curve and coefficient of determination determined from measured data (left) and for data normalized to a specimen age of 28 days: , (6) In accordance with the data presented in Fig. 2 and Eqs. (4−6), which were obtained from experimental research, it is evident that the normalized (28 days) results of both materials have similar values.
Measured fatigue data were normalised to concrete age of 28 days.

Finally, the bandwidth occupation and bandwidth efficiency of MEBPSK are analyzed according to different bandwidth definitions, a comparison is made between MEBPSK and EBPSK under the same conditions and, by analysis and experiment, it is shown that bandwidth efficiency of MEBPSK can be log2N times that of EBPSK according to -60dB definition, N is the integer power of 2, which obviously improves the data rates greatly under the same condition.
