SUMMARY:ECE Research Seminar Series: Dr. Arindam Sanyal\, Arizona State University
DESCRIPTION:Machine Learning for In-Sensor Artificial Intelligence and High-performance Circuit Design\n\n\n\n\n\n\n\nAbstract: This talk focuses on application of machine-learning (ML) for imparting intelligence to sensing devices as well as lead to high-performance circuit design. As wireless sensors are more widely adopted\, the volume of data produced by these devices are expected to reach thousands of petabytes/month. Transmitting this large volume of data over the cloud for processing will potentially emerge as a communication bottleneck and increase latency of decisions. Transmitting naively all data generated by a wearable medical device is also costly in terms of power/energy- transmitter is usually the highest consumer of energy in a sensor (at least 10~20x more energy than sensing). Key to addressing this data deluge is to increase capabilities sensing devices to process information locally and have on-device inference capabilities\, such as through embedding AI capabilities into the wearable device that will allow extraction of key information from the sensor data. There needs to be balance between what can be processed locally on-device with low power/energy and how to optimally decide the volume of data communication from the device (to cloud as an example). The barriers to this approach lie in the computational complexity of AI algorithms that makes it challenging to fit AI models on wearables with limited resources. Some of the answers might lie in going back to early days of signal processing in silicon – developing analog circuit techniques for AI development which will require collaborative innovations in both AI model development and analog circuit design techniques. In this talk\, I will present our research on developing analog AI circuits and their demonstrations with use cases from health monitoring to IoT. \n\n\n\nThe second part of this talk will present ML approaches for enhancing performance of data converters. ML has the potential to emerge as an alternative to current signal processing based complex calibration algorithms for enhancing data converter performance in advanced processes. By learning an efficient representation of the input and data converter behavior\, a simple neural network can correct data converter errors arising from multiple sources of non-idealities with similar accuracy as complex calibration algorithms but with a much lower hardware cost. \n\n\n\nArindam Sanyal\n\n\n\nBio: Arindam Sanyal is currently an assistant professor in the School of Electrical\, Computer and Energy Engineering at Arizona State University. Prior to this\, he was an analog design engineer with Silicon Laboratories and assistant professor in State University of New York.

SUMMARY:ECE Research Seminar Series: Dr. Junyi Zhao
DESCRIPTION:Soft Electronics & Systems for Sensing\, Perception\, and Feedback\n\n\n\n\n\n\n\nAbstract: Wearable technologies can support health span only when they are comfortable\, motion-robust\, and able to convert raw signals into actionable\, intuitive information. My research focuses on materials-device-system co-design of soft electronic systems that integrate three core functions\, sensing\, perception\, and feedback\, across healthcare and embodied interaction applications. \n\n\n\nIn this talk\, I will first introduce wearable systems for women’s health\, including maternal monitoring of cardiac and uterine contraction biopotentials in clinical settings for early risk detection of preterm birth. This platform leverages soft polymeric electrodes and textile-integrated interfaces designed for stable and wireless electrophysiological recording. Second\, I will present garment-integrated electrophysiology platforms for ambulatory biopotential monitoring in daily life\, including electrocardiography (ECG) and skeletal muscle electromyography (EMG) during strenuous activities such as exercise and water sports\, with an emphasis on maintaining signal fidelity under body motion. Third\, I will describe embodied tactile interfaces that enable robust touch and gesture recognition under deformation\, combining pressure mapping with personalized recognition for intelligent human-computer interaction. Fourth\, I will discuss semiconductor material processing and advanced manufacturing approaches for intrinsically soft optoelectronic devices\, including stretchable light-emitting diodes (LEDs) that provide low-burden\, glanceable visual feedback on wearables and everyday objects. Finally\, I will discuss future advances in intelligent wearables for personalized women’shealthcare and safe human-robot interaction. \n\n\n\nJunyi Zhao\n\n\n\nBio: Dr. Junyi Zhao is a Postdoctoral Scholar at Stanford University\, where he works with Professor Zhenan Bao to develop intelligent wearable electronics and medical robotics.

SUMMARY:MS&E Special Seminar: Dr. Angela R. Hight Walker
DESCRIPTION:UW-Madison Department of Materials Science and Engineering welcomes Dr. Angela R. Hight Walker. Her seminar\, “Novel Instrumentation for 2D Material Characterization: Combined Helicity-Resolved Magneto-Optical with Magneto-Transport”\, will take place on Tuesday\, June 9\, 2026\, from 2:30-3:30 p.m. in MSE 265. \n\n\n\n\n\n\n\nBio \n\n\n\nDr. Angela R. Hight Walker is a senior scientist at the National Institute of Standards and Technology (NIST)\, recognized for her leadership in pioneering optical spectroscopies to characterize quantum materials. A current focus area is using optical signatures to study magnetic order.  Over three decades\, she has led a dynamic research team unraveling the complexities of low-dimensional materials\, contributing nearly 200 multidisciplinary publications at the inface of physics\, chemistry\, and materials science. She is a Fellow of the American Physical Society (APS) and the American Association for the Advancement of Science (AAAS) and OPTICA. Dr. Hight Walker is also a leading figure in nanotechnology standardization efforts\, contributing to ISO Technical Committee 229 Nanotechnologies and VAMAS TWA 41 and 42 committees. Beyond her scientific achievements\, Dr. Hight Walker is deeply committed to fostering inclusivity and diversity in science. She just finished the Chair-line for the Committee on the Status of Women in Physics (CSWP)\, one of APS’s oldest committees. She boldly advocates for science accessibility\, engaging young and under-resourced individuals through demonstrations and lectures\, while mentoring over 50 students and postdoctoral researchers\, many from underrepresented groups. \n\n\n\nAbstract \n\n\n\nRaman spectroscopy\, imaging\, and mapping are powerful non-contact\, non-destructive optical probes of quasiparticles and fundamental physics in graphene and other related two-dimensional (2D) materials\, including layered\, quantum materials. An amazing amount of information can be quantified from the Raman spectra\, including layer thickness\, disorder\, edge and grain boundaries\, doping\, strain\, thermal conductivity\, magnetic ordering\, and unique excitations such as magnons and charge density waves. Most interestingly for quantum materials is that Raman efficiently probes the evolution of the electronic structure and the electron-phonon\, spin-phonon\, and magnon-phonon interactions as a function of laser energy and polarization\, temperature\, and applied magnetic field. Our unique magneto-Raman spectroscopic capabilities will be detailed\, enabling polarization- and spatially-resolved optical measurements while simultaneously measuring electrical transport in a back-gated graphene Hall bar device.Raman and electrical data from an hBN-graphene-hBN device operating in the quantum Hall regime will demonstrate our novel capabilities. Also\, results from a series of 2D magnetic material systems showing multi-quasiparticle interactions observable with our unique measurement system will be highlighted. Lastly\, the importance of detailed alignment\, calibration and reference materials will be demonstrated quantifying the ability to differentiate chiral phonons as a function of temperature and laser wavelength.

SUMMARY:ECE Research Seminar Series: Associate Professor Yei Hwan Jung\, Hanyang University
DESCRIPTION:Materials and Fabrication Strategies for Strain-Invariant Stretchable Electronics and Displays\n\n\n\n\n\n\n\nExact event time and location to be announced\n\n\n\n\n\n\n\nAbstract: Stretchable electronic systems often suffer from strain-induced performance drift\, which hinders reliable operation in practical settings. Under tensile deformation\, stretchable interconnects can lose conductivity; semiconductor devices can exhibit shifts in their current–voltage and transfer characteristics; and radio-frequency components can experience frequency detuning. Stretchable displays further face variations in fill factor and effective resolution\, which can distort rendered images and videos. Conventional stretchable touch sensors also struggle to decouple in-plane strain from out-of-plane pressure\, limiting sensing accuracy.This seminar will present recent advances toward deformation-invariant stretchable electronics and displays\, including semiconductor devices\, RF circuits\, displays\, and touch sensors that preserve their electrical and optical characteristics under elongation. I will highlight materials innovations and device-level design strategies that suppress strain sensitivity\, including strain-stable functional materials and architectures that mechanically decouple or compensate for deformation. I will also discuss design methodologies that maintain constant geometry or response under load. The talk will conclude with open challenges and future research directions toward robust\, manufacturable\, and truly strain-invariant stretchable systems. \n\n\n\nYei Hwan Jung\n\n\n\nBio: Professor Yei Hwan Jung is an Associate Professor in the Department of Electronic Engineering at Hanyang University. He received his M.S. and Ph.D. from the University of Wisconsin–Madison and his B.S. from the University of Illinois Urbana-Champaign.His research group addresses key challenges in semiconductors\, packaging\, and emerging electronics by advancing materials\, devices\, and manufacturing strategies\, with a focus on advanced packaging\, next-generation semiconductors\, deformable displays\, and wearable/implantable systems
