Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

Advanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

From Bug to Feature: Harnessing Cross‐Sensitivity for Multiparametric Luminescence Sensing

Advanced Functional Materials, EarlyView.
Cross‐sensitivity in luminescence sensing is reframed from a limitation into a resource for multiparametric detection. Using ruby microspheres as a model system, cross‐sensitivity is quantitatively assessed and exploited through linear discriminant analysis, enabling simultaneous, correction‐free pressure and temperature sensing with a single ...

Bio‐Inspired Multimodal Hardware Front‐End Enabled by 2D Floating‐Gate Memory for UAV Perception

Advanced Functional Materials, EarlyView.
A MoS2/h‐BN /graphene floating‐gate memory underpins a bio‐inspired multimodal front end that integrates visual, inertial, and airflow cues. A 4 × 4 FG memory array encodes temporal intensity differences, while IMU‐ and airflow‐driven threshold modulation suppresses self‐motion artifacts, enabling fast, low‐power, robust autonomous UAV tracking and ...

Cell Calcification Models and Their Implications for Medicine and Biomaterial Research

Advanced Healthcare Materials, EarlyView.
Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,

Novel 3D‐Printed Biophotonic Scaffold Displaying Luminescence under Near‐Infrared Light for Photopharmacological Activation and Biological Signaling Compound Release

Advanced Healthcare Materials, EarlyView.
Despite significant efforts in developing novel biomaterials to regenerate tissue, only a few of them have successfully reached clinical use. It has become clear that the next generation of biomaterials must be multifunctional. Smart biomaterials can respond to environmental or external stimuli, interact in a spatial‐temporal manner, and trigger ...

Gain- and offset-compensated non-inverting SC circuits

2000 IEEE International Symposium on Circuits and Systems. Emerging Technologies for the 21st Century. Proceedings (IEEE Cat No.00CH36353), 2002
A new scheme which can greatly reduce the effects due to finite open-loop gain and DC offset and has no limitation on the input is presented. The principle based on work by Nagaraj et al. (1987) is to perform a preliminary charge transfer operation preceding every desired charge transfer operation, thus obtaining a close approximation of the finite ...

Gain- and offset-compensated switched-capacitor filters

1991 IEEE International Symposium on Circuits and Systems (ISCAS), 1991
Novel gain- and offset-compensated (GOC) switched-capacitor bilinear and biquadratic sections using a two-phase clock are presented. Theoretical analysis and simulation results show that the frequency responses of these circuits have very low sensitivity to the finite operational amplifier (op-amp) gain, while the time responses are insensitive to ...

Area-efficient gain- and offset-compensated very-large-time-constant SC biquads

[Proceedings] 1992 IEEE International Symposium on Circuits and Systems, 2003
A signal flow graph analysis of K. Nagaraj's (1989) very large time-constant biquads based on charge splitting is described. With the addition of offset-storing capacitors, gain- and offset-compensated biquads are obtained. By applying the charge differencing technique, the biquads can be made very area efficient.

On-Focal Plane Analog-To-Digital Conversion With Detector Gain And Offset Compensation

SPIE Proceedings, 1989
Hardware fabrication has been initiated on a test IC which has 32 channels of amplifiers, low pass anti-aliasing filters, 13-bit analog-to-digital (ND) converters per channel and a digital multiplexer. The single slope class of ND conversion is described, as are the unique variations required for incorporation on-focal plane.

Embedded anti-aliasing in switched-capacitor ladder filters with variable gain and offset compensation

IEEE Journal of Solid-State Circuits, 2002
A combination of continuous-time and switched capacitor integrators in a simulated LC lossless ladder yields a response with suppressed aliasing without the use of continuous-time prefiltering. Fabricated in a 0.35-/spl mu/m CMOS process, a fifth-order Cauer low-pass filter for a W-CDMA cellular phone receiver has a cutoff frequency of 1.92 MHz and ...
