Garment manufacturing system and method
Various methods for detecting moisture in briefs compatible with high volume manufacturing are disclosed. The embodiments herein facilitate protection of the method of adding moisture sensing to a diaper, but could also be used to add sensing to pads and bandages. The primary design intent is optimal moisture detection and low per unit cost. Electrodes within a garment measure electrical properties of the electrodes to determine if the item has contacted moisture. The target moisture is urine, however, other sources and types of moisture can also be sensed. Additional analysis capabilities can be added by selecting particular electrodes or add materials that may react with chemical components of the moisture. Applications of the research Include monitor of incontinence using smart brief (e.g. diaper); monitor perspiration, bleeding, or failure of the protective garment; and monitoring exposure of an item to moisture, including but not limited to inanimate items.
1. A method of manufacturing a garment, comprising:
configuring one or more print stations to each have a drying capacity;
preparing a predetermined combination of conductive materials for use in forming one or more electrodes;
the one or more print stations printing the conductive materials onto poly film thereby forming a waterproof pre-printed poly film using a predetermined printing method, thereby forming one or more electrodes;
the one or more print stations drying the pre-printed poly film;
incorporating the pre-printed poly film into the garment;
arranging a physical connection to the electrode surface through the permeable layer on an upper edge of the garment;
one of more contacts piercing the permeable layer; and
configuring each contact with multiple points thereby increasing reliability of the one or more contacts.
