The 21st century technological inventions that bring about what rapid changes

1, can monitor vital signs of the "pill" - can be swallowed "stethoscope" EnteroPhone.

This is called the "EnteroPhone" physiological state monitoring (PSM) pill contains a number of specially designed, can "listen" to the heartbeat. "EnteroPhone" physiological state monitoring (PSM) pill contains some special, can "listen" to the sound of the heartbeat and the sound of lung activity of the mini loudspeaker, as well as a can measure the temperature of the nucleus of the body of the mini-thermometer. It is currently the only pill-based detector that can track three key vital signs simultaneously.

2. The "underwater drone" that lets ordinary people explore the deep ocean, the Trident undersea explorer.

OpenROV gives the Trident a number of new features that set it apart from other submersibles: a depth of up to 100 meters; a triple-thruster design; and the ability to dive to a depth of up to 10 meters. The triple-thruster design facilitates precise operation, and the smooth shape makes movement more stable and faster.

3. Portable and accurate 3D scanner - the small and compact Eora 3D.

The Eora 3D achieves greater accuracy with a device the size of a carbonated bottle, which connects to a smartphone and uses a green laser with a wavelength of 520 nanometers to scan around the object and reconstruct a high resolution image of the object on the smartphone. The device is connected to a smartphone and uses a green laser with a wavelength of 520 nanometers to scan around the object and reconstruct a high-precision 3D model of it on the smartphone.

4. A camera that generates its own power -- the self-sufficient "Eternal Camera.

The camera can take one picture per second and display it on an external display. Next, the team hopes to reduce the size of the camera while increasing its speed and resolution.

5. A better tablet for the blind -- the "Holy Braille" tablet.

Existing technology allows Braille displays to realize full-page browsing like tablet computers, but the cost is extremely high, and researchers hope to expand it to realize full-page displays and keep the cost between $1,000 and $2,000.
