Methods and devices for treating skin include a skin-contacting portion, an actuator and a processor, wherein activation of the actuator causes surface acoustic waves of Rayleigh, 'pseudo' Rayleigh types to be produced on the skin around the actuator. In a location which is under the actuator, the actuator produces tension and repulsion of skin particles. These surface acoustic waves can be used to provide treatment to the skin, including wound healing, non-adhesion of bandages, reduced infection, reduced pain and cosmetic enhancements. The skin-contacting portion may be a patch or bandage, a glove, a hand-held device, or any other suitable configuration. The actuator is incorporated into the skin-contacting portion.

System and method for surface acoustic wave treatment of skin

Methods and systems are provided for treatment of medical devices using surface acoustic waves (SAW) of Rayleigh, 'pseudo' Rayleigh and Lamb type. In some embodiments, use of such SAW is controlled such that relative velocity of bacteria is achieved wherein the vibration amplitude of the bacteria is smaller than a Z-potential repulsive zone of the bacteria, thus preventing biofilm formation on the medical devices. In some embodiments, systems of the present invention are powered by body movements, and may also provide a feedback loop for control of parameters. In some embodiments, the medical devices of the present invention are comprised of piezoelectric material, and act as self-actuators for the system.

System and method for surface acoustic wave treatment of medical devices

A urinary catheter clip-on device applies surface acoustic waves of Rayleigh-Lamb and/or Love type to a urinary catheter for preventing biofilms on the catheter surfaces. The bacteria is forced to move relative to the vibrating catheter surface. The amplitudes of bacteria vibrations are in nanometer range. The relative motion of bacteria results in bacteria quorum sensing, and disrupts the bacteria attachment process. The method is preventive as surface acoustic waves create low acoustic energy and bacteria is not killed.

Acoustic add-on device for biofilm prevention in urinary catheter

Apparatus and method for sterilization of liquid includes a liquid container containing a liquid and having a piezoceramic ring that is connected to a power supply system. Power supply system supplies electric signals to the piezoceramic ring that are transformed into mechanical waves and cause vibrations in the liquid.

Apparatus for sterilizing a liquid with focused acoustic standing waves

An apparatus, system and method for preventing or treating biofilm associated with catheters. A piezo-ceramic element may be attached to a catheter, and a vibration processor may be connected to the piezo-ceramic element. The vibration processor may provide electric signals that generate acoustic vibrations in the piezo-ceramic element, causing vibrations in or around the catheter. These vibrations may be particularly administered to disperse microbe colonies, thereby preventing or inhibiting formation of biofilm that may lead to infections. Vibrations may be amplified significantly due to resonance conditions in the catheter balloon, which may be powerful enough to be used to disperse microbe colonies that have grouped around the catheter or are attempting to do so.

As part of the present invention, a motion detector for detecting motion inside of a body may include a first oscillator to produce an electrical scanning signal and a second oscillator to produce an electrical Doppler signal. A vibrating element may vibrate in response to the scanning and Doppler signals. A vibration transducer may receive vibrations reflected from a structure inside the body and may convert the reflected vibrations into an electrical signal. Doppler shifts between the transmitted and received vibrations may be used to estimate the velocity of the structure inside the body.

System and method for detection of motion

Apparatus for providing linear motion to a generally flat flexible material, comprising: (a) at least one piezoelectric ceramic motor situated on a first side of the flat flexible material and having a contact surface which contacts the flat flexible material and which imparts said linear motion; and (b) a bearing surface situated on a second side of the flat flexible material opposite said contact surface.

Conveying means and method

The present invention provides a device and method for monitoring and detecting a fetal heartbeat that can be employed by ordinary people with minimal, if any, training, such as expectant mothers. The device can monitor and detect a fetal heartbeat with minimal positioning along the female body at the pregnant portion (the womb) as the device is configured to transmit and receive energy waves at wide angles. The device is economical and is preferably designed for domestic use, outside of the hospital or clinical setting. Specifically, the invention is based on a unique configuration of piezoelectric elements in cooperative configuration with a series of oscillators that is able to transmit and receive ultrasonic waves simultaneously The configuration allows for an optimal scanning range at an unlimited number of angles.

A micromotor for moving a body including at least one rectangular piezoelectric plate having long and short edges and first and second faces, electrodes attached to the first and second faces and a ceramic spacer attached to the center of a first one of the edges and operative to be pressed against the body. A resilient force is applied to the center of a second edge opposite the first edge, whereby the ceramic spacer is pressed against the body. At least some of the electrodes are electrified by either an AC or an asymmetric unipolar pulsed voltage.

The first short edge of the first plate is adjacent and substantially parallel to the first short edge of the second plate. Resilient force is applied to a portion of each plate, pressing the ceramic spacer against the surface of the body. A voltage source electrifies at least some of the electrodes with an excitation voltage.

A multiaxis rotation device for rotating a curved element about two, orthogonal axes is provided. The device includes two pairs of motors and two pairs of axis defining units, where each pair of axis defining units are placed on opposite ends of a line along one of the two orthogonal axes. The axis defining units each include a support for the curved element and apparatus for pressing the support against and pulling the support away from the curved element. The pulling away occurs when the motors corresponding to the axis defining unit are not providing rotation about the axis defined by the axis defining unit.
