Wang Teng, founder of Today's Relaxation Technology, has published an explanation for why the company's first device is a smart ring. He stated that sleep problems cannot be solved by a single device alone; the optimal solution lies in understanding one's own condition and developing a healthy lifestyle. He pointed out that previous smart wearable devices have suffered from pain points such as short battery life, inaccurate monitoring, and skin irritation and discomfort from wearing, and that some smart rings also use plastic material for the inner ring, which may likewise cause allergies. Earlier, Wang Teng unveiled the ISHO Ring smart ring at a launch event. The device features an inner and outer double-ring aerospace-grade titanium alloy construction, integrates 116 components, and debuts industry-first features such as full-dimensional ambient light sensing, with a starting price of 1,799 yuan.
