The present invention promotes the activation of various physiological functions according to the stimulation of the body by superimposing a reference wave microcurrent of a low frequency and a main wave microcurrent of a high frequency into a preset pattern, or by additionally superimposing a multiple superimposed wave microcurrent discretely having a frequency of a larger magnitude sequentially than the main wave microcurrent and applying it to living organisms, and enables that the use and expandability can be increased by providing an additional configuration in which a multifunctional portable housing that can select AC electric stimulation and DC electric stimulation is worn on the wrist of the human body, thereby enabling the application of an electrical stimulation tailored to the body or disease/health condition of a user.

Wearable devices, systems, methods and architectures for sensory stimulation and manipulation and physiological data acquisition

A garment with prepositioned, definite sensory stimulating devices attached. These sensory stimulating devices include, but are not limited to, electrical stimulation, audio and physical stimulation such as localised force generation, compression, constriction, vibration, and surround sound. Predetermined and defined actuators allow the wearer to receive tissue, nerve and/or muscle stimulation and/or contraction so that the stimulation is precise as determined by its ability to conform to the scientific methodology of repeatability, reproducibility and reliability; this being due to consistency of actuator positioning in one or multiple locals on the human body. A personal surround sound can also be integrated to the garment to ensure the wearer is always in the optimal position relative the speakers. These actuators can be force generators within the garment for the wearer to feel impact or apparatus or electrodes included in the garment to locally constrict and increase pressure on the wearer.

Methods and apparatus for stimulation of biological tissue

In illustrative implementations of this invention, interferential stimulation is precisely directed to arbitrary regions in a brain. The target region is not limited to the area immediately beneath the electrodes, but may be any superficial, mid-depth or deep brain structure. Targeting is achieved by positioning the region of maximum envelope amplitude so that it is located at the targeted tissue. Leakage between current channels is greatly reduced by making at least one of the current channels anti-phasic: that is, the electrode pair of at least one of the current channels has a phase difference between the two electrodes that is substantially equal to 180 degrees. Pairs of stimulating electrodes are positioned side-by-side, rather than in a conventional crisscross pattern, and thus produce only one region of maximum envelope amplitude. Typically, current sources are used to drive the interferential currents.

Selective high frequency spinal cord modulation for inhibiting pain with reduced side effects, and associated systems and methods

Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

A neuromodulator includes an electromagnetic (EM) wave generator configured to generate EM waves remote from a patient and to direct the EM waves to one or more target regions within the patient. Frequencies of the EM waves fall outside a range of frequencies that activates neurons. Intersection of the EM waves in each target region creates envelope-modulated electric and magnetic fields having one or more frequencies that fall within the range of frequencies that activates neurons. The neuromodulator includes control circuitry configured to control parameters of the EM waves produced by the EM wave generator. The neuromodulator may use feedback based on one or more of patient input and/or sensing of physiological signals in order to close the loop and control the EM waves.

This application discloses an improved approach for delivering Tumor Treating Fields (TTFields) at a therapeutically effective strength to the infratentorial regions of the brain. A first set of electrode elements is positioned on top of the head and a second set of electrode elements is positioned on the back of the neck. Third and fourth sets of electrode elements are positioned on the lower back right and the lower back left portions of the scalp, respectively. Applying an AC voltage between the first and second sets of electrode elements generates a generally vertical field in the infratentorial regions of the brain; and applying an AC voltage between the third and fourth sets of electrode elements generates a generally horizontal field in those regions.
