| چکیده | ||
| ساختارهای آگزتیک (ضریب پواسون منفی) ساختارهایی هستند که وقتی در جهت طولی تحت کشش (فشار) قرار می‌گیرند در جهت عرضی دچار انبساط (انقباض) می‌گردند.در این کار، اثر هندسه ساختار شش‌ضلعی آگزتیک روی ضریب پواسون آنتحت بارگذاری کششی بزرگ به روش تجربی و عددی مورد بررسی قرار گرفته و نشان داده شده که مکان و سفتی اتصال‌های چرخشی دو پارامتر جدید مهمی هستند که روی مقدار ضریب پواسون تاثیرگذار هستند. ضریب پواسون با سفت‌ترشدن اتصال‌های چرخشی و دور شدن آن‌ها از وسط ساختار افزایش پیدا می‌کند. بنابراین، با تغییردادن مکان و سفتی اتصال‌های چرخشی به راحتی می‌توان ساختارهای شش‌ضلعی آگزتیک با ضرایب پواسون متفاوت را به دست آورد که امکان ساخت حسگرهای پیزومقاوم با حساسیت‌های متفاوت را فراهم می‌کند. حسگر آگزتیک پیزومقاوم کششی با حساسیت بالا برای کرنش‌های پایین از ترکیب لاستیک سیلیکون و الیاف کربن خردشده ارائه شده‌است. کرنش جابجایی مقداری از کرنش می‌باشد که در آن ضریب پواسون ساختار از منفی به مثبت تغییر علامت می‌دهد. حسگرهای آگزتیکی ارائه‌شده، عملکرد فوق‌العاده خوبی تا کرنش تغییر دارند و بعد از آن رفتار معمولی از خود نشان می‌دهند. این بهبود در خواص حسی حدود 150% (بر حسب فاکتور اندازه) در قیاس با حسگرهای معمولی می‌باشد. | ||

| چکیده [English] | ||
| Auxetic structures (negative Poisson’s ratio) are a group of materials that expand (contract) under tensile (compression) longitudinal loading. In this work, the effect of re-entrant auxetic structure geometry on Poisson’s ratio was investigated under large tensile loading experimentally and numerically and showed that the location and stiffness of rotation joints are two new important parameters affecting the value of Poisson’s ratio. Poisson's ratio increases as the rotation joints tighten and move away from the center of the structure. Therefore, by changing the location and stiffness of the rotation joints, it will be easy to obtain re-entrant auxetic structures with different Poisson's ratios, which makes it possible to build piezoresistant auxetic sensors with different sensitivities. A highly sensitive, stretchable piezoresistant auxetic sensor made of silicon rubber and chopped carbon fibers is proposed for low strain values. The main feature of this sensor is its high sensitivity for strains less than 6%, which previous works have been unable to detect this range of strains. Shifting strain is the value of strain in which the Poisson's ratio of the structure changes from negative to positive. The provided auxetic sensor performs exceptionally well until the shifting strain and then performs as conventional sensors. This improvement in sensing performance is about 150% (in terms of gauge factor). | ||
