The security service provider Alarm.com has unveiled a doorbell that can be operated without contact. The camera used by the “Touchless Video Doorbell” registers when a visitor steps onto the doormat. An acoustic signal then sounds in the house. Moreover, a notification is sent to the owner's smartphone and a video recording begins. The owner can then speak to the guest. The doorbell displays a notification instructing the visitor of its function. What's more, Alarm.com sells a doormat with the doorbell that also allows visitors to ring the bell without touching.
Researchers from the Korea Institute of Science and Technology and the Gwangju Institute of Science and Technology have developed a disposable kit that can detect airborne viruses in 50 minutes without needing to send samples back to the lab. Similar to a pregnancy test, the kit works by collecting and concentrating the airborne virus particles on a glass fiber pad. Capillary action then pushes the virus to flow into the detection zone, where the particles bind to nanoprobes conjugated to virus-specific antibodies. This makes it possible to identify the virus.
The Amsterdam-based design group GG-loop has designed a new form of flexible, high-density urban housing that uses prefabricated timber and modules based on a biophilic principle. Biophilic design means that the relationships between nature, human biology and the built environment are taken into consideration in the building process as well as thereafter. The proposed project, named Mitosis, is scalable and modular, creating a regenerative housing ecosystem with a positive ecological footprint.
The French start-up Pollen Robotics has presented its further developed open-source robot Reachy, which can now be remote-controlled using a VR headset. The humanoid robot is ideal for use in research and as a service robot. Reachy was equipped with a better camera and a more powerful processor. The robot sends video signals via the camera to the user's VR headset. Users can control the robot's arms and hands from their own home so that it performs certain tasks for them.
The British student start-up Lava has developed an environmentally-friendly washing machine that collects outflowing shower water and reuses it for the washing cycle. The washing machine features a portable water tank that can be removed and used as a shower mat. In this way, water is collected and shampoo or dirt particles are cleaned off using a filter. The design of this washing machine makes it possible to save costs and the entire product is easy to transport. What's more, reusing the shower water saves extremely large amounts of water.
