As shown in FIG. 1, a rectenna receives microwaves emitted from an antenna and converts DC power into an intelligent membrane structure actuator through a power allocation and distribution circuit. to the membrane actuator, or in the power allocation and distribution logic circuit, direct current power is transferred to and stored in a thin-film solid-state microbattery, and the stored direct current power is transferred back to the intelligent membrane structure actuator. Month. Here, the rectenna, the power allocation and distribution logic circuit, the membrane structure actuator and the thin film solid state micro battery are integrally implemented in one package.

The rectenna is distributed in piezoelectric actuators in the form of patches.

The microwave emitted from the antenna contains a control signal which is tuned to control the shape of the actuator.

Power allocation and distribution circuitry is embedded in the actuator and enables intelligent power usage.

Figure 2 is an exploded perspective view schematically showing the configuration of an intelligent membrane structure actuator driven by a microwave according to the present invention. As shown in FIG. 2, the microwave driven flexible smart membrane includes a piezo polymer, a copper ground plate, a dielectric film, and a thin film rectenna circuit. -film rectenna circuit). This thin film rectenna circuit includes a butterfly filter, impedance matching circuitry and schottky diodes.

The patch rectenna can be implemented to generate high voltage-low current using piezoelectric material as a smart material, and can also be implemented to generate low voltage-high current using magneto strict material.

The figure shows the concept of shape control using an electro or magneto-active polymer film with altered CNTs. Thin film rectenna patches convert microwave power into direct current power. This DC power is used to align pre-oriented modified CNTs that are on when the power is off, so that the power is turned on and along the field line. This creates an in-plane tension for shape control.

According to the present invention, the microwaves emitted from the antenna are received by the rackenna and the converted DC power is transferred to the intelligent membrane structure actuator through the power allocation and distribution logic circuit, or the DC power in the power allocation and distribution logic circuit. Microwaves, including rectennas, power allocation and distribution logic circuits, membrane structure actuators, and thin film solid state micro batteries that are delivered to and stored in the thin film solid state microbattery, and the stored direct current power is passed back to the intelligent membrane structure actuators. Driving Intelligent membrane structure actuator, the microwave powered actuator is wirelessly powered by microwave and can be driven at low power because it is light weight.
