Journal ArticleDOI
Microstructured Porous Pyramid-Based Ultrahigh Sensitive Pressure Sensor Insensitive to Strain and Temperature
Jun Chang Yang,Jin-Oh Kim,Jinwon Oh,Se Young Kwon,Joo Yong Sim,Da Won Kim,Han Byul Choi,Steve Park +7 more
TL;DR: An ultrahigh sensitive capacitive pressure sensor based on a porous pyramid dielectric layer (PPDL) is reported, which was drastically increased to 44.5 kPa-1 in the pressure range <100 Pa, an unprecedented sensitivity for capacitivepressure sensors.
Journal ArticleDOI
Pressure Insensitive Strain Sensor with Facile Solution-Based Process for Tactile Sensing Applications
Jinwon Oh,Jun Chang Yang,Jin-Oh Kim,Hyunkyu Park,Se Young Kwon,Serin Lee,Joo Yong Sim,Hyun Woo Oh,Jung Kim,Steve Park +9 more
TL;DR: This work presents an all-solution processable pressure insensitive strain sensor that utilizes the difference in structural change upon the application of pressure and tensile strain to differentiate between shear stress and normal pressure.
Journal ArticleDOI
Mechanically transformative electronics, sensors, and implantable devices
Sang Hyuk Byun,Joo Yong Sim,Zhanan Zhou,Juhyun Lee,Raza Qazi,Raza Qazi,Marie C. Walicki,Kyle E. Parker,Matthew P. Haney,Su Hwan Choi,Ahnsei Shon,Graydon B. Gereau,John Bilbily,Shuo Li,Yuhao Liu,Woon-Hong Yeo,Jordan G. McCall,Jianliang Xiao,Jae-Woong Jeong,Jae-Woong Jeong +19 more
TL;DR: This work applied temperature-triggered tuning of mechanical characteristics of device platforms to create personal electronics with variable stiffness and stretchability, a pressure sensor with tunable bandwidth and sensitivity, and a neural probe that softens upon integration with brain tissue.
Journal ArticleDOI
In vivo Microscopic Photoacoustic Spectroscopy for Non-Invasive Glucose Monitoring Invulnerable to Skin Secretion Products.
TL;DR: By obtaining the microscopic spatial information of skin during the spectroscopy measurement, the skin region where the infrared spectra is insensitive to skin condition can be locally selected, which enables reliable prediction of the blood glucose level from the photoacoustic spectroscopic signals.
Journal ArticleDOI
E-cadherin and LGN align epithelial cell divisions with tissue tension independently of cell shape
Kevin C. Hart,Jiongyi Tan,Kathleen A. Siemers,Joo Yong Sim,Beth L. Pruitt,W. James Nelson,Martijn Gloerich +6 more
TL;DR: The findings indicate that E-cadherin plays a key role in sensing polarized tensile forces across the tissue and transducing this information to the spindle orientation machinery to align cell divisions.
