after experiencing important innovations, the field of electronic switches has gradually transitioned from traditional mechanical buttons to capacitive touch technology, and this technology has gradually become the mainstream control method for various electronic devices. zhuhai yingsi integrated circuit design co., ltd. (hereinafter referred to as "yingsi integrated"), located in xiangzhou district, zhuhai city, has gone a step further on this basis and is the first in the industry to launch low-cost human electrostatic induction touch technology using air conduction media, providing the ultimate cost value for the downstream of the industrial chain and opening up new near-field human electrostatic induction application scenarios.
significantly reduce product costs
human body electrostatic induction touch technology is widely used in daily electronic products and is one of the mainstream ways of human-computer interaction today. before the emergence of ins integrated, this technology had been in a commercial state with the help of springs as the conductive medium. zheng guandong, general manager of ins integrated, introduced that in the home appliance industry, all products will be designed with digital tubes or lcd screens for display. such devices have a certain thickness, which means that there is a certain distance from the touch panel to the circuit board. with air as the conductive medium, human body electrostatic induction is easily disturbed. therefore, the industry usually uses springs as the conductive medium to achieve human body electrostatic induction. "in the early commercial stage, home appliance manufacturers did not have a strong demand for removing springs. this is because the thickness of commonly used digital tubes or lcd screens is in the range of 8 mm to 12 mm. the human body electrostatic induction technology that relies on air as the conductive medium cannot meet commercial application scenarios in a short time. in addition, the unit price of the product at that time was high, and the cost of other materials was also high, and the cost proportion of the spring was not sensitive." zheng guandong said.
with the rapid development of the industry, the demand for removing springs has become stronger and stronger. digital tubes or lcd screens can now be customized, and the thickness has dropped to about 2 mm, creating a space for technical iteration for the commercial application of human electrostatic induction technology. in addition, with the rapid changes in the commercial environment, products require extreme cost solutions. it is understood that the cost of each spring is 0.05 yuan to 0.1 yuan, accounting for 10% to 20% of the total cost of the circuit board. the cost of the spring has become more and more sensitive.
"the human body has static electricity. when it touches the panel, it forms an equivalent capacitor with the circuit board. this technology can detect the potential change of the equivalent capacitor and identify the touch operation." zheng guandong said, "in addition, we use an 8-bit processor solution, combined with high-precision circuits and optimized algorithms. the sensing height can reach 9 mm, while the industry can only reach about 5 mm, and the cost is much higher than ours."
at present, touch controllers have been widely used in many fields such as smart electronics, smart home, automotive electronics, engineering medical equipment, etc. "we chose to enter the field of home appliances, which has a stable first-tier market and a huge maintenance market. we predict that the annual market size will be nearly 10 billion yuan." zheng guandong said, "this technology can also be applied to smart switches, smart watches and other fields. our entire technology has completed the process from '0' to '1'. in the future, in the process from '1' to '10', related technologies will be iterated faster. the goal is to have 100 million home appliances using our technology within 5 years."
rapid development of multiple tracks
it took insi integrated one and a half years from project initiation to successful development of human body electrostatic induction touch technology. "during this period, we have taken a new path and made new things, which is closely related to our r&d team." zheng guandong introduced that insi integrated's r&d team accounts for more than half of the company's total number of employees. the core team has many years of experience in related industry design and successful commercialization. the company's r&d investment accounts for nearly 80% of total expenditures, and "investment in technological r&d will be increased in the future."
in addition, insigma has also entered into teaching and research products, and has reached cooperation with many general high schools and vocational high schools to build relevant laboratories. in addition to providing all-in-one computing machines, it also includes a platform-level practice system. "based on the industry end, we help schools solve problems related to integrated circuit design teaching. all courseware content is trained in accordance with corporate standards and related r&d processes, and is more practical." zheng guandong said, "our core point is to enable students to independently complete the development of a 55-nanometer chip."
in zheng guandong's view, the growth of the company is inseparable from the strong support of xiangzhou district. "what impressed me most was the talent policy of xiangzhou district, which provided free venues and financial support for our early local entrepreneurial team, which was very helpful to us and saved a lot of entrepreneurial costs." zheng guandong said.
"xiangzhou district has abundant relevant industrial resources and a complete industrial chain. we also hope that the district can build a platform to enable more communication and interaction between enterprises," said zheng guandong.
"now our technology has been mass-produced in the client, and we will continue to deepen the human body electrostatic induction technology in the future. in the horizontal direction, we will expand the current air conduction range to 12 mm, covering all types of digital tubes and lcd screens on the market. in the vertical direction, we will make the current conventional induction coils larger and improve the near-field distance sensing to replace the infrared probe market and make the new application scenarios more compatible with the existing scenarios." zheng guandong said, "we hope that in the future in the home appliance track, when people mention electrostatic induction related technologies, they will think of our products and our brand."
