The previous Olympic Games are not only a stage for athletes to display, but also an arena for scientific and technological equipment. Although it is full of shortcomings, at least in terms of technology, there are many aspects of the Rio Olympics that make people look forward to it.

Hykso: Another manifestation of the Olympic champion dream

Hykso is a boxing sensor with a built-in accelerometer and gyroscope that can achieve full 3D tracking 1,000 times per second and send the captured data to a smartphone application, allowing coaches and athletes to more intuitively understand the status of their punches, thereby improving their performance. In fact, Hykso has been recognized by the U.S. Olympic Committee. At the same time, U.S. Olympic Committee officials also stated that wearable devices are being used to monitor athletes' data in different sports such as diving, gymnastics, wrestling, and track and field.

Smart glasses used by the USA Cycling National Team

Solos is another wearable device that has gained Olympic-level recognition, and the U.S. Cycling Team has used the smart glasses for training. The design of Solos is very similar to Google Glass, but it is specifically designed for cycling. It has a built-in heart rate sensor that can monitor the cyclist's heart rate, calories burned and other data, and display it on the head-up display lens, and then provide suggestions based on the cyclist's status. In addition, it can also realize functions such as navigation and making and receiving calls.

Ernesto Martinez, one of the developers of Solos, said that London double Olympic champion and multiple world cycling champion Sarah Hammer is a loyal supporter of Solos. The glasses can quantify her training and help her challenge speed and rhythm, and can also receive coaching instructions remotely.

The archery event uses electronic targets for the first time, with an accuracy of 0.2 mm

This Olympic Games will use technology to record results in archery competitions for the first time. Previously, the results of archery competitions have been judged by the human eye using special telescopes. Omega, the official timekeeping partner of the Olympic Games, has introduced a new archery target with a built-in scanning system. Athletes no longer have to wait anxiously for results to be announced and can focus on shooting the next arrow.

When the arrow hits the target, the two scanners will run vertically and horizontally respectively to calculate the distance between the arrow and the center point of the target. The system has an accuracy of 0.2 mm, which is beyond the reach of the human eye. At the same time, the system runs very fast and can give results within 1 second after the target is hit.

Zika virus-proof clothing

The ongoing Zika virus epidemic in South America has left many participating parties with lingering fears. This mosquito-borne virus may induce microcephaly in newborns, and South American countries are the hardest hit by the virus.

As of early July, Lake Rodrigo, the venue for the Brazilian Olympic rowing competition, was still seriously polluted, and the hygiene of the Olympic competition venue was questioned. For this reason, many national team uniforms are designed with long pants and long sleeves to prevent skin exposure. For example, South Korea claims that special materials are added to its Olympic team uniforms during the production process to prevent the Zika virus.

The materials and technology of the track and field uniforms have been upgraded and have undergone hundreds of hours of wind tunnel testing

Nike AeroSwift technology is made of innovative and environmentally friendly lightweight recycled polyester, which is reduced to the lightest weight by transforming and simplifying the structure. Improved manufacturing processes combine all-around stretch knitting, breathable engineered mesh, and AeroBlades to deliver the ultimate in performance. The Chinese track and field team will use AeroBlades technology, which has undergone hundreds of hours of wind tunnel testing and is distributed in key areas of clothing. It can guide air around athletes and create stronger wind resistance for Nike track and field equipment.

The golf scoreboard is equipped with a radar system to display speed, distance and other data

After more than a century, golf returns to the Olympics. To this end, Omega has specially introduced a new scoreboard for this event. The new scoreboard will be set up on four dedicated tees in the ground and equipped with a radar measurement system. After golfers tee off, the scoreboard will capture instant information and display it to spectators, allowing them to follow the action closely. In addition to the player's name and current score, the scoreboard will display data such as bat speed, projected distance and bat height in real time.

The museum will display a 3D printed replica of the statue of Zeus

The long-lost Seven Wonders of the World have been brought back to life through a partnership between Stratasys and the Millennium Gate Museum. They used 3D printing technology to create a nearly identical statue of Olympian Zeus. People familiar with history know that the statue is a huge ancient Greek god sitting on a carefully carved cedar throne (inlaid with ebony, ivory, gold, and precious stones). It was designed and made by the Athenian artist/sculptor Phidias in 432 BC (he was also responsible for the construction of the Parthenondivision).

Stratasys worked with the 3D Center at Kennesaw State University (KSU) to create the replica using a Stratasys Fortus 900mc Production 3D printer. It claims to be 3 times faster than traditional 3D processing, and the finished product is smoother and more realistic.

Fortus 900mc uses Fused Deposition Modeling technology, which can melt engineering-grade thermoplastic materials under the guidance of CAD. Its form is quite stable and strong, and can be painted and decorated with ivory gold and other decorations as needed.

HP releases backpack that can charge laptops

HP's new Powerup Backpack looks a lot like a standard backpack, but it can charge a full-size laptop thanks to its 22,400mAh battery, which can also charge your smartphone up to 10 times. The canvas design facilitates ventilation and heat dissipation, and it also has a thermal sensor to prevent the battery from overheating. FAA regulations prohibit any battery over 100 watt-hours from being carried in carry-on luggage, and the HP Powerup backpack has an 84-watt-hour battery, so it should be fine.
