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.
The Coast Guard Administration (CGA) yesterday said it had deployed patrol vessels to expel a China Coast Guard ship and a Chinese fishing boat near Pratas Island (Dongsha Island, 東沙群島) in the South China Sea. The China Coast Guard vessel was 28 nautical miles (52km) northeast of Pratas at 6:15am on Thursday, approaching the island’s restricted waters, which extend 24 nautical miles from its shoreline, the CGA’s Dongsha-Nansha Branch said in a statement. The Tainan, a 2,000-tonne cutter, was deployed by the CGA to shadow the Chinese ship, which left the area at 2:39pm on Friday, the statement said. At 6:31pm on Friday,
The Chinese People’s Liberation Army Navy’s (PLAN) third aircraft carrier, the Fujian, would pose a steep challenge to Taiwan’s ability to defend itself against a full-scale invasion, a defense expert said yesterday. Institute of National Defense and Security Research analyst Chieh Chung (揭仲) made the comment hours after the PLAN confirmed the carrier recently passed through the Taiwan Strait to conduct “scientific research tests and training missions” in the South China Sea. China has two carriers in operation — the Liaoning and the Shandong — with the Fujian undergoing sea trials. Although the PLAN needs time to train the Fujian’s air wing and
Taiwanese celebrities Hank Chen (陳漢典) and Lulu Huang (黃路梓茵) announced yesterday that they are planning to marry. Huang announced and posted photos of their engagement to her social media pages yesterday morning, joking that the pair were not just doing marketing for a new show, but “really getting married.” “We’ve decided to spend all of our future happy and hilarious moments together,” she wrote. The announcement, which was later confirmed by the talent agency they share, appeared to come as a surprise even to those around them, with veteran TV host Jacky Wu (吳宗憲) saying he was “totally taken aback” by the news. Huang,
The American Institute in Taiwan (AIT) put Taiwan in danger, Ma Ying-jeou Foundation director Hsiao Hsu-tsen (蕭旭岑) said yesterday, hours after the de facto US embassy said that Beijing had misinterpreted World War II-era documents to isolate Taiwan. The AIT’s comments harmed the Republic of China’s (ROC) national interests and contradicted a part of the “six assurances” stipulating that the US would not change its official position on Taiwan’s sovereignty, Hsiao said. The “six assurances,” which were given by then-US president Ronald Reagan to Taiwan in 1982, say that Washington would not set a date for ending arm sales to Taiwan, consult
