A biometric sensor includes a body surface sensor and an e-field signal transmitter. The body surface sensor create a drive-sense signal at a first frequency based on one or more sensing parameters. When operably coupled to a body via one or more electrodes, the body surface sensor provides the drive-sense signal to the body and detects an effect on the drive-sense signal based on electrical characteristics of the body. The body surface sensor generate a data signal based on the detected effect, wherein the data signal represents the body’s electrical characteristics. The e-field signal transmitter generates an outbound signal reference at a second frequency based on the data signal and one or more transmit parameters. The e-field transmitter drives the outbound reference signal to the body, wherein the outbound reference signal is transmitted within at least a portion of the body as an outbound e-field signal at the second frequency.

An analysis method for analyzing pressure exerted by a body portion and/or of a human prosthesis includes: sampling data generated by the body portion and/or the prosthesis during a threshold calibration period at a sampling frequency in a condition of use thereby obtaining an array of sampled data of at least one sensing unit; providing at least one threshold value of the sampled data for the condition of use and storing the least one threshold value in a memory unit; comparing at the sampling frequency the sampled data with the at least one threshold value to obtain calibrated data, and storing the calibrated data in the memory unit and/or sending the calibrated data to a computing device if the calibrated data is greater than the at least one threshold value. A sensing device for sensing the pressure exerted by a body portion and/or the human prosthesis is also provided.

A detection system includes an acquisition unit, a calculation unit, a determination unit and a correction unit. The acquisition unit acquires measurement information from a load distribution sensor that detects a distribution of a load received from a sole of a subject. The calculation unit calculates a total load value of a sole region corresponding to the position of a sole of one leg of the subject, based on the measurement information. The determination unit determines an action state of the one leg based on the total load value. The correction unit starts to offset the total load value using an offset filter that decreases an offset amount with time elapse, in response to a determination that the action state is a first action state where the total load value tends to increase and is equal to or larger than a preset determination value.

The present invention relates to a method for measuring an exercise, in which method the electrical signals caused by active muscles are measured with a measuring device and response is given from the physical performance with a perceivable signal. In the method in accordance with the invention by measuring and analyzing EMG activities of muscles or EMG activities of muscles and movements of the body quantities describing the physical performance and/or the result of the physical performance are calculated or evaluated.

A sensing portion of the tension type smart shoe unit is arranged to extend across the width of thea sole of a wearer so that foot pressure applied through the sole is exerted thereon, and a connection portion of the tension type smart shoe unit is fixed by connection to a connecting portion of a circuit block. Thus, even when the foot pressure exerted is biased to the left or right while the wearer is walking, only a portion where the pressure is biased is not sensed in contrast with a conventional case in which piezoelectric sensors are mounted, but the sensing portion is deformed, and the magnitude of an electrical output signal corresponding to the deformation is calculated using an equation of a relationship with a load. Consequently, the amount of foot pressure may be precisely measured even with a simple configuration.

A custom foot orthotic and a system and a method for designing of a custom foot orthotic. The method includes: receiving 3D scan data of the patient's foot; receiving plantar pressure scan data of the patient's foot; establishing a desirable pressure distribution; generating an underfoot elevation profile relative to an elevation profile of the patient's foot in the 3D scan data; determining an internal density profile of the resulting foot orthotic 3D model by superimposing the desirable pressure distribution over the resulting foot orthotic 3D model and reducing or increasing density in regions of the foot orthotic 3D model based on the difference between an expected pattern of support and the desirable pressure distribution; and outputting the 3D model of the custom foot orthotic.

An insole including a base; an electronic element provided to the base; a connection line configured to extend from the electronic element and to pass through the base; and a cover provided on a top surface of the base to cover the electronic element and configured to be separable from the base.

A system and method for a multichannel voltage recording device is described. A multichannel voltage recording device comprises at least three electrodes disposed across a conductive material. The electrodes are configured to be coupled to a skin of a user. A frame comprises the conductive material that is configured to receive a driven right leg (DRL) signal based on the voltage signals from the at least three electrodes.

A device that non-invasively detects objects beneath or around the foot or a foot position and transmits signals which are processed and then output via an output device on a skin surface not affected by a neurological deficit, such as the hands or thighs. This device is suitable for subjects with diabetic neuropathy who have lost sensation in their feet and are at risk of punctures, cuts or other physical damage and at risk of sprains, strains or falls due to lack of an ability to detect objects underfoot and foot position.

Provided is a smart insole including a support layer; a plurality of pressure sensors provided to the support layer and configured to sense a pressure; a plurality of vibrators provided to the support layer and configured to generate a vibration; and a controller configured to determine a center of pressure (COP) based on a pressure sensed by each of the plurality of pressure sensors and to control the plurality of vibrators based on a positional relationship between a setting point and the COP.
