The design of the piezoelectric film is relatively easy, the piezoelectric ceramic materials with appropriate thickness, appropriate performance is designed according to the cavity’s resonant frequency, The back of the circuit is relatively easy to handle, as the Piezoelectric material’s pressure disappears, the charge will disappear, there will be no voltage, To take advantage of the piezoelectric material to generate electricity, the piezoelectric ceramic chip is in parallel with a capacitor, The value of capacitance is selected according to the performance of piezoelectric ceramic materials and the voltage required by the behind circuit, then, a low-power DC-DC converter is followed to get a constant voltage.

Much research has been undertaken for new anode materials in place of carbon to improve energy density for rechargeable lithium-ion batteries [1].
The Li-ion anodes derived from tin-based materials received considerable interest because the theoretical capacity of the tin-based material is 994 mAhg-1 and it can easily store 50% reversible lithium more than the carbon-based lithium intercalation materials in principle [2-8].
Carbonaceous materials experience small volume expansion for lithium intercalation (9% graphite) and have good cycling characteristics.

The braking force between the brake disc and the brake pad is equal to the tension of controlled material at that time.
When the disturbance tension increases, the controlled material holds up the adjustment wheel.
It results in that the speed of material reel unwinding turns faster, and the tension is reduced.

This has created a short supply of wood materials because it takes time for trees to grow before they can be used.
Moreover, using sago waste can help to reduce the amount of residues as well as be used as partial substitution of raw materials in various industrial applications.
The materials were placed in a mat forming wooden box with the dimension of 30 cm x 30 cm and manually formed.
