Journal ArticleDOI
Stretchable Active Matrix Temperature Sensor Array of Polyaniline Nanofibers for Electronic Skin
Soo Yeong Hong,Yong Hui Lee,Heun Park,Sang Woo Jin,Yu Ra Jeong,Junyeong Yun,Ilhwan You,Goangseup Zi,Jeong Sook Ha +8 more
TL;DR: A stretchable polyaniline nanofiber temperature sensor array with an active matrix consisting of single-walled carbon nanotube thin-film transistors is demonstrated and gives mechanical stability under biaxial stretching, and the resultant spatial temperature mapping does not show any mechanical or electrical degradation.
Journal ArticleDOI
A three-dimensional meshfree method for continuous multiple-crack initiation, propagation and junction in statics and dynamics
TL;DR: In this article, a three-dimensional mesh-free method for arbitrary crack initiation and propagation is proposed to ensure crack path continuity for non-linear material models and cohesive laws based on a local partition of unity.
Journal ArticleDOI
Stretchable Array of Highly Sensitive Pressure Sensors Consisting of Polyaniline Nanofibers and Au-Coated Polydimethylsiloxane Micropillars
Heun Park,Yu Ra Jeong,Junyeong Yun,Soo Yeong Hong,Sangwoo Jin,Seung Jung Lee,Goangseup Zi,Jeong Sook Ha +7 more
TL;DR: The facile fabrication of a stretchable array of highly sensitive pressure sensors that are capable of noninvasively detecting human-pulse waveforms from carotid and radial artery and the potential application is demonstrated for wearable and artificial electronic skin devices.
Journal ArticleDOI
An extended isogeometric thin shell analysis based on Kirchhoff-Love theory
Nhon Nguyen-Thanh,N. Valizadeh,Minh Nguyen,Hung Nguyen-Xuan,Xiaoying Zhuang,Pedro M. A. Areias,Goangseup Zi,Yuri Bazilevs,L. De Lorenzis,Timon Rabczuk,Timon Rabczuk +10 more
TL;DR: An extended isogeometric element formulation (XIGA) for analysis of through-the-thickness cracks in thin shell structures is developed in this article, where the discretization is based on Non-Uniform Rational B-Splines (NURBS).
Journal ArticleDOI
A meshfree method based on the local partition of unity for cohesive cracks
Timon Rabczuk,Goangseup Zi +1 more
TL;DR: In this paper, a mesh-free method based on the local partition of unity for cohesive cracks is presented, where cracks are described by a jump in the displacement field for particles whose domain of influence is cut by the crack.
