PIEZOELECTRIC PIPE:

- Internal channeling of water circulation.

- External encapsulation of the pipe where the piezoelectric generators are included.

- Bearings for the internal channel to rotate with respect to the external part.

- Fins in internal channel to rotate, as a consequence of water flow.

- Mechanical elements for performing micro pulsations in piezoelectric elements.

PIEZOELECTRIC MODULE:

PZT piezoelectric element with dimensions 1,5 mm x  1,5 mm x 10 mm

g33 = 0,035 Vm/N Applying a force of F= 0,2 N = 0,02 Kg

  - Vout = 0,035 x 0,01 x ( 0,2 / (0,0015 x 0,0015 )) = 31,11 V

After AC/DC converter each piezoelectric module Mji,i  has Vout = 30 V

The speed at which the triggering force F is applied on all the piezoelectric modules Mji,i is set by the activation plate is regulated to give an output current Iout = 1,5 mA

PIEZOELECTRIC GENERATOR:

Space between piezoelectric modules = 1,5 mm

Element + space = L + space = 1,5 + 1 = 2,5 mm = 0,0025 m

Number of piezoelectric elements = 2,5 m / 0,0025 m = 1.000

Matrix Generator = 1 row x 1,000 columns, then:

  - Iout = 1.000 piezoelectric x 1,5 mA = 1.000 piezoelectric x 0,0015 A = 1,5 A

  - Vout = 30 V

  - Pout = 1,5 A x 30 V = 45 W

Considering an efficiency = 85 %. Pout = 38,25 W
