The smart watch market is fiercely competitive, with battery life troubling the major manufacturers. Matrix Industries, a Silicon Valley startup, has developed a smartwatch powered by body temperature to solve the problem of battery life. According to U.S. media reports on June 29, in order to bring its products to market, Matrix has raised $ 12.3 million (about 83.38 million yuan) and plans to raise another $ 5 million (about 33.9 million yuan) for New product development. Matrix's founders are Akram Boukai and Douglas Tham, both Ph.D. students in chemistry at the California Institute of Technology. When the two are still studying in the campus, they have already started to develop thermoelectric technology. The company developed a smartwatch called PowerWatch in 2016. According to the official website, this smart watch "powered by body temperature" will never need an external power cord. Boukai said, "As people's movement, body temperature, PowerWatch will produce more electricity." This smart watch also tracks sleep, steps and calories. Products priced at 139 to 179 US dollars (about 942 to 1213 yuan between), will be listed in September and October. According to data released by Strategy Analytics, a market research firm, in the first quarter, Apple surpassed Fitbit and ranked first in the wearable device market. However, Apple's Apple Watch has been widely criticized for its short standby time and PowerWatch has the advantage in this regard.
