Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a flexible antenna module for wireless energy transmission; and more particularly to a flexible antenna module for wireless energy transmission, which enables the antenna's size adjustable to conform an individual's outer portion.

2. Description of the Related Art

Electrical stimulator combines the principles of Chinese traditional Point Percussion Therapy and western TENS (Transcutaneous Electrical Nerve Stimulation). The stimulator uses micro electric current to stimulate specific acupuncture points to achieve the health care effect. That is it can stimulate the self-cure mechanism of the body with an electric current having suitable intensity and frequency continuously, gently stimulating the nerve, the muscle and the cell. On clinical uses, the method of treatment is divided into the Transcutaneous Electrical Nerve Stimulation (TENS) and the Electrical Muscle Stimulation (EMS).

The electrical stimulation has been widely utilized for the function of recovery. Recently, as a result of the breakthrough of the micro electron technology, the micro mechanical and electrical technology, the biological material and the biological compatible seal technology, the electrical stimulator tends to have a small and implanted form.

FIG. 1 is a conventional implanted electrical stimulator comprising an in vivo electrical stimulating module 10 and an in vitro energy-transmitting module 12. The in vivo electrical stimulating module 10 includes a circuit board 100; an in vivo energy-transmitting coil 102 and a pair of positive/negative electrodes 104 provided on the circuit board 100 and a biological compatible polymer layer 106 covering the whole in vivo electrical stimulating module 10. The in vitro energy-transmitting module 12 includes an in vitro control module 120 and an in vitro energy-transmitting coil 122. The in vitro control module 120 will drive the in vitro energy-transmitting coil 122 to emit wireless energy. The wireless energy will be received by the in vivo energy-transmitting coil 102 and converted by the circuit board 100 into a voltage source. The converted voltage source will be applied on the positive/negative electrodes 104 to generate an electrical stimulating current.

As mentioned above, the conventional implanted electrical stimulator transmits the energy from an external antenna module to an in vivo implanted electrical stimulating element via radio frequency (RF) and receive the energy by an internal electronic component to automatically generate an electrical stimulation, rather than stimulating the nervous muscle with an electrical line penetrating through the skin, thus can reduce the probability of wound infection. However, the energy needed by the implanted electrical stimulating device is unidirectionally transmitted into the implanted electrical stimulating device via a fixed-size antenna. That is, the energy is transmitted to the in vivo electrical stimulating module via an external energy-transmitting antenna to stimulate the nervous muscle. In operation, this energy-transmitting method may suffer from the displacement of the implanted electrical stimulating element or the electromagnetic interference from surrounding environment and thus change the properties of the energy-transmitting circuit, thereby causing to transmit excessive energy to result in heat-generating from the implanted electrical stimulating element, or causing to transmit too little energy to result in abnormal operation or even malfunction, thereby further causing unnecessary damage to the human body. In addition, effective detection of the position of the implanted electrical stimulating element and provision of effective energy-transmission are also general issues encountered for the implanted electrical stimulators.

In brief, the method for energy transmission of the conventional implanted electrical stimulator has the following disadvantages:

1. The antenna's size is fixed, and unsafe and un-comfortable in utilization.

2. The exact position of the implanted electrical stimulator is not easy to detect.

3. Control of the power transmission does not come easy.

4

. Properties of the energy transmission circuit easily suffer from electromagnetic interference from surrounding environment.

Accordingly, there is an improved antenna technique for energy transmission provided.

The electrical stimulating signal control module 64 comprises a first wireless radio frequency interface circuit 641, an adjustable power control circuit 642 and an output control circuit 643. The flexible annular antenna 20, which is deformed to conform a living body's outer portion, is provided to wirelessly transmit energy. The antenna deformation detector 51 is used to detect the deformation of the flexible annular antenna 20. The antenna deformation compensation circuit 52 depends on the deformation of the flexible annular antenna 20 to provide a compensation power to the power controller 53. The first wireless radio frequency interface circuit 641 is used to drive the flexible annular antenna 20 to emit energy and convert a sense signal received by the flexible annular antenna 20 into a first electronic signal. The adjustable power control circuit 642 depends on the first electronic signal to determine the optimum power control mode for energy transmission.

Next, in step 705, the external module for energy transmission 60 detects the feedback signal by the flexible annular antenna 20. When the flexible annular antenna 20 detects no feedback signal, go to step 706, the driving power of the flexible annular antenna 20 is fine-tuned, then steps 700 to 705 are repeated, until the flexible annular antenna 20 detects the feedback signal. When the flexible annular antenna 20 detects the feedback signal, go to step 707, the feedback signal is converted to the first electronic signal by the first wireless radio frequency interface circuit 641, and the first electronic signal is sent to the adjustable power control circuit 642. The adjustable power control circuit 642 depends on the first electronic signal to determine the inclination angle and the distance between the antenna for energy transmission 621 and the flexible annular antenna 20. In step 708, the adjustable power control circuit 642 depends on the aforesaid parameters to determine the optimum power control mode for energy transmission. Next, in step 709, the output control circuit 643, such as a digital control circuit, depends on the optimum power control mode for energy transmission to send an output power to the power controller 53. The power controller 53 depends on the compensation power provided by the antenna deformation compensation circuit 52 to output a compensated driving power to the first wireless radio frequency interface circuit 641 to drive the flexible annular antenna 20 for wireless energy transmission. Next, go to step 701, the energy is received by the second wireless radio frequency interface circuit 622 to convert to the second electronic signal, and depending on the second electronic signal determines whether the energy is sufficient to activate the electrical stimulating control circuit 624. If the result is yes, go to step 711, activating the electrical stimulating control circuit 624, and starting up the electrical stimulating.
