Poor sleep can be attributed to many causes, including shift work, stress, snoring or even sleep apnea – a disorder in which the sleeper temporarily stops breathing. Until now, only a sleep laboratory could determine whether a patient is suffering from sleep apnea or related sleep disturbances.
In a traditional sleep laboratory, the patient is observed while sleeping for at least one night, connected to cables and observed by a large number of measuring instruments and cameras. Researchers at the Fraunhofer Institute for Integrated Circuits IIS in Erlangen have now developed a mobile sleep lab for home use.
SomnoSENS consists of a small box that is worn attached to the body during sleep and observes vital functions. Four adhesive electrode pads are used to record an electrocardiogram (ECG), while a finger clip measures the patient’s blood oxygen level and pulse rate. A nasal clip and expandable belts around the upper torso monitor breathing, and a movement sensor in the device identifies the patient’s body position and registers how much he or she moves. “The device is attached to the body during sleep and does not hinder sleep comfort due to its miniature size,” Herbert Siegert from IIS assures. “SomnoSENS records and stores the data, and transmits them to the base station via a Bluetooth wireless interface. The physician can later evaluate the stored information to make an evidence-based diagnosis.”
Heart patients simply wear a small, lightweight device on their body. It records heartbeats via a 3-channel ECG, identifying minimum and maximum heart rates as well as arterial fibrillation. At the same time, the device records movement. A physician can evaluate, for instance, the heart rate in connection with physical effort, thus simplifying the diagnosis. The system also permits recovery time to be determined after physical exercise. The data are transferred via a home gateway to an Internet portal where the physician can access the information remotely. A range of optional components can be added to the system to measure other vital data such as blood pressure, weight or blood sugar level.ActiSENS – Keeping active
During the day, the current score can be displayed on the device at any time. In the evening, the accumulated data for the day can be transferred to a PC via Bluetooth and analyzed in greater depth according to previously selected parameters. The data can also be forwarded to a physician for evaluation. In this way it can be determined, for example, whether a patient’s prescribed physical therapy is producing the desired results.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
