Oct 12, 2026The ProblemWearable health trackers often rely on batteries that add bulk, require charging, and can make continuous monitoring difficult. Our IdeaResearchers developed smart glasses with self-powered sensors that turn tiny facial movements, including blinks and jaw clenches, into electrical signals that can identify everyday behaviors. Why It MattersThe technology could transform ordinary glasses into low-power health monitors that track cardiovascular signals and behaviors throughout the day without requiring users to regularly recharge them. Our TeamProfessor Nivedita Arora; Professor Nabil Alshurafa; Master’s students Raj Dave, Yung-ching Lai, and Jovanis ProdanichFrom blinking and smiling to jaw clenching and eyebrow raising, faces are constantly in motion—and generating tiny amounts of energy along the way.
Now, Northwestern Engineering researchers are putting that energy to work.

Patient-centered financial navigation assistance helps reduce financial toxicity among cancer patients - Medical Xpress
Among cancer patients, the high financial cost of cancer care is a prevalent problem. This financial burden is also associated with potentially harmful behavioral strategies that patients might use to cope with costs, such as delaying or forgoing treatment and skipping medications. Collectively, researchers refer to this impact as financial toxicity.
Continuous glucose monitors help type 2 diabetes patients spend 5 more hours a day in healthy blood sugar range - Medical Xpress
Continuous glucose monitors (CGMs) could transform diabetes management for millions of Americans with type 2 diabetes who don't take insulin, according to findings published in the New England Journal of Medicine. The clinical trial found that adults using CGMs spent approximately five additional hours each day within their target blood sugar range compared with those receiving routine care. Nearly twice as many CGM users also achieved an A1c level below 7%, a common treatment goal for people with diabetes.

“Beyond Detecting Cancer Recurrence: Can Whole-Genome Sequencing-Based ctDNA Monitoring Help Personalize Adjuvant Treatment? An exciting new study published in The Oncologist highlights the clinical potential of Signatera Genome, a whole-genome sequencing (WGS)-based, tumor-informed circulating tumor DNA (ctDNA) assay, not only for detecting molecular residual disease (MRD), but also for potentially informing adjuvant treatment decisions.
