Relying on independently developed PVDF ceramic piezoelectric sensing technology and flexible knitting sensing technology, we have collaborated with domestic smart elderly care pioneers such as Maidong Medical and Sicheng Intelligent, taking the lead in entering the fields of smart elderly care and smart rehabilitation. Currently, Weilin Technology's vital sign monitoring sensing technology has been applied in nearly 20 elderly care institutions and more than 10 medical institutions across the country, serving over 1,000 elderly people and rehabilitation groups. We have established strategic cooperative relationships with more than 10 domestic smart elderly care platforms to help them build a sound health management system. Meanwhile, we assist well-known domestic furniture enterprises and manufacturers in achieving rapid intelligent upgrading and digitalization of store experiences.
