by Rice University A sample of Rice University’s ‘magnetoelectric’ film atop a bed of uncooked rice. Rice neuroengineers created the bi-layered film to power implantable neural stimulators that are approximately the size of a grain of rice. The film converts energy from a magnetic field directly into an electrical voltage, eliminating the need for a...
KURT YAEGER, M.D. MATERIALS, RADIOLOGY The company EXO Imaging out of Redwood City, CA recently emerged from stealth mode to announce the development of a novel technology called PiezoelectricMicromachined Ultrasonic Transducers (pMUT) for ultrasound imaging. EXO Imaging is bringing together advances in micromachined materials and artificial intelligence to enhance both the ultrasound probe as well as the receiver that a clinician uses to visualize the ultrasound images....
