(SD2025-068) Low-Cost, Scalable Passive Sensors: a battery-free wireless general sensor interface platform
Researchers from UC San Diego present a fully-passive, miniaturized, flexible form factor sensor interface titled ZenseTag that uses minimal electronics to read and communicate analog sensor data, directly at radio frequencies (RF). The technology exploits the fundamental principle of resonance, where a sensor's terminal impedance becomes most sensitive to the measured stimulus at its resonant frequency. This enables ZenseTag to read out the sensor variation using only energy harvested from wireless signals. UCSD inventors further demonstrate its implementation with a 15x10mm flexible PCB that connects sensors to a printed antenna and passive RFID ICs, enabling near real-time readout through a performant GUI-enabled software. They showcase ZenseTag's versatility by interfacing commercial force, soil moisture and photodiode sensors.
Newborn Biomarkers of Cumulative Autism Risk Factors
Researchers at the University of California, Davis have identified DNA methylation biomarkers in placenta, as well as maternal and newborn blood, allowing early autism diagnosis and risk assessment.
Genetic Polymorphisms Linked to Age-Related Eye Disorders and Drug Response
Researchers at UC Irvine have identified genetic polymorphisms associated with disease progression and responsiveness to treatment with Tetracosapentaenoic acid (24:5 n-3) for age-related eye disorders such as age-related macular degeneration (AMD), diabetic retinopathy and glaucoma. These variations found in the ELOVL2 gene are associated with AMD progression and the varying responses individuals have to AMD treatments, including preventative measures. Additionally, these genetic variations have applications in human identification.
