Under the direction of Charles DiMarzio, an associate professor in the departments of electrical and computer engineering and mechanical and industrial engineering, the students created the technology for a wireless wrist device that automatically alerts emergency responders should the gadget detect a sudden change in the user’s vital signs or speed of movement, as from a fall.
The innovative technology was developed for the team’s engineering senior capstone project. The team members included Darren Nunes, Brian Rosenberg, Jon Sarafinas, Chris Udall and Max Flaherty.
The wireless device, designed to resemble a wristwatch, monitors vital signs, including oxygen levels and heart rate, and wirelessly transmits the information so those responding to an emergency know as much as possible prior to arriving at the scene.
The idea behind the device came from the Flaherty family’s experience with another, less technologically advanced product. A family member wearing a non-automated emergency alert device suffered fatal internal injuries after falling down a set of stairs.
“I wanted to design something that a person can easily wear and has the capacity to alert emergency responders automatically if the user becomes unconscious," said Flaherty. "Our device has the potential to save more lives."
The design of a non-invasive device that allows users to live safely and independently was a priority for the students, who spent more than 2,000 hours on the project.
“No other commercial system currently integrates wrist-worn fall detection, plus vital sign and emergency monitoring in the way that this system does,” said Udall.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
