Tiny sensor analyzes biomarkers in sweat

EPFL’s Adrian Ionescu  has developed a miniature chip  that analyzes biomarkers in sweat to understand a wearer’s health. It is the basis of a modular system that can measure sodium and potassium concentrations (that signal dehydration); body temperature and pH (to detect bacteria and risk factors for other illnesses); chlorine levels (as an early indication of […]

Vibrating sensors could detect TBI, disease, infection in drop of blood

Purdue’s Jeffrey Rhoads, George Chiu, and Eric Nauman have developed a method to identify biological markers in small amounts of blood that they believe can detect diseases and infections and conditions such as traumatic brain injury at an early stage. An array of sensors  enable statistical-based detection The small, cheap vibrating sensors use a piezoelectrically actuated resonant microsystem to […]
