A micro deep drawing experiment is performed using micro thin foil materials (Al-1100, SUS-304).
Fig. 5 Modal testing result of system Table 2 Natural frequency data of system Mode Natural Frequency 1st 300 Hz 2nd 525 Hz 3 rd 1,000 Hz 4 th 2,450 Hz Drawing Test of Al-1100 and SUS-304 Materials The micro deep drawing tests are performed with aluminum (Al-1100) and SUS-304 thin foils.
The thickness of thin foil materials is a 100�.
But we can get a good result in the SUS-304 thin foil material (Fig.6-(b)).

Manganese dioxides are promising supercapacitor materials due to the low cost of raw materials, environmentally friendlier than other transition metal oxide systems, non-toxicity criteria and high performance [9].
Then, these functional groups act as the initiation points for absorbing external materials.
