AcurtexTM CoreTM, patent-pending technology, enables the increase of skin conductance via electrically inducing sudomotor reaction (sweat gland innervation) making the acquisition of high quality heart’s signals via textile possible.

It is a breakthrough technology which allows us to overcome the major obstacle – very low skin conduction - that prevented, until now, the use of textile (hence: garments) for health monitoring.

This is because textile sensing of electrophysiological signals requires high conductivity between the textile and skin; which in orthodox non-textile systems (such as those used in hospitals, clinics) is achieved by the use of highly conductive substances (including gel applied between the sensors and skin). The application of such lubricants is practically impossible when using textile and if used, would dry out with extended use. This is extremely inconvenient for the wearer for continuous daily use (feels wet) and requires applying gel before every use – which can be impractical.

This is what our technology mitigates - we were able to augment skin conductivity without the use of any lubricant and/or chemical substance, making the use of textile for long term monitoring a reality.
We are using a physiological phenomenon called sudomotor reaction (production of sweat which is a highly conductive fluid) for our use. We succeeded in inducing a sudomotor reaction by delivering a transdermal electrical stimulus over the skin which increases conductance via thermoregulatory sweating. Therefore we are able to not only increase the conductance, but also to quantitively control it, ensuring high signal quality.

In the cellular level, sudomotor function is controlled by a division of sympathetic systems relating to nerve fibers that control the activity of sweat glands.

Sudomotor nerves are C-fibers, thin unmyelinated or poorly myelinated, with primarily cholinergic neurotransmission, wherein the neurotransmitter at the ganglion is acetylcholine - the principal neurotransmitter of the parasympathetic nervous system. The electrical stimuli sensitize the post-ganglionic neurons to secrete acetylcholine, which in turn activates the sweat glands to produce sweat; the latter being highly conductive and so increases skin conductance.
