Taiwanese inventor and university professor Cai Yen-hsin (蔡彥欣) won a total of five gold medals at the British Invention Show (BIS) which concluded in London on Saturday, with his pacifier thermometer also receiving a double-gold award, and a water purifier machine receiving a platinum award.
Cai is an assistant professor at Taipei’s Chengshih University of Science and Technology’s electronic engineering department.
The negative hydrogen ion water purifier Cai designed was awarded one gold and one platinum award by the BIS jury.

Manufactured by Mega Sun Biomedical Corp, the water purifier uses a dozen filter cores to remove heavy metals and toxins, and produces purified water with a redox potential of minus-700, compared with between minus-200 and minus-300 achieved by other water purifiers on the market, Cai said, adding that ionized water is an antioxidant that counters cellular aging.
Cai’s purifier is available for about NT$50,000, and its filter cores can process 1,500 liters of water before needing replacement, which means a liter of water costs just a few New Taiwan dollars to purify, with the negative electric charge, oxygen and trace elements produced by the machine ensuring the water is pollutant-free, he said.
Another of Cai’s inventions that won two medals at the show is the baby pacifier equipped with a thermometer, which he calls the “Happy Baby’s Magical Pacifier.”
If a baby’s temperature surpasses 39°C, the thermometer triggers LED lights alerting the parents, Cai said.
The pacifier can also play soft music to help a baby get to sleep, Cai said.
Three other inventions Cai submitted to the show that won gold medals were a multifunction motorcycle helmet, an emergency-escape indicator light, and a nanotechnology water-and-corrosion-resistant membrane.
Cai said that he would like to work with medical researchers to improve patient health by providing better-quality drinking water.
China has reserved offshore airspace in the Yellow Sea and East China Sea from March 27 to May 6, issuing alerts usually used to warn of military exercises, although no such exercises have been announced, the Wall Street Journal (WSJ) reported yesterday. Reserving such a large area for 40 days without explanation is an “unusual step,” as military exercises normally only last a few days, the paper said. These alerts, known as Notice to Air Missions (Notams), “are intended to inform pilots and aviation authorities of temporary airspace hazards or restrictions,” the article said. The airspace reserved in the alert is
South Korea is planning to revise its controversial electronic arrival card, a step Taiwanese officials said prompted them to hold off on planned retaliatory measures, a South Korean media report said yesterday. A Yonhap News Agency report said that the South Korean Ministry of Foreign Affairs is planning to remove the “previous departure place” and “next destination” fields from its e-arrival card system. The plan, reached after interagency consultations, is under review and aims to simplify entry procedures and align the electronic form with the paper version, a South Korean ministry official said. The fields — which appeared only on the electronic form
More than 6,000 Taiwanese students have participated in exchange programs in China over the past two years, despite the Mainland Affairs Council’s (MAC) “orange light” travel advisory, government records showed. The MAC’s publicly available registry showed that Taiwanese college and university students who went on exchange programs across the Strait numbered 3,592 and 2,966 people respectively. The National Immigration Agency data revealed that 2,296 and 2,551 Chinese students visited Taiwan for study in the same two years. A review of the Web sites of publicly-run universities and colleges showed that Taiwanese higher education institutions continued to recruit students for Chinese educational programs without
A bipartisan group of US senators has introduced a bill to enhance cooperation with Taiwan on drone development and to reduce reliance on supply chains linked to China. The proposed Blue Skies for Taiwan Act of 2026 was introduced by Republican US senators Ted Cruz and John Curtis, and Democratic US senators Jeff Merkley and Andy Kim. The legislation seeks to ease constraints on Taiwan-US cooperation in uncrewed aerial systems (UAS), including dependence on China-sourced components, limited access to capital and regulatory barriers under US export controls, a news release issued by Cruz on Wednesday said. The bill would establish a "Blue UAS
