Problems solved by technology
However, existing charging technologies have their own limitations
For example, the cardiac pacemaker implanted in the human body has high requirements for the durability of the implanted battery power supply, but the existing battery technology is difficult to meet, which leads to patients having to undergo surgery to replace the cardiac pacemaker every once in a while. pacemaker
Another example is digital products such as mobile phones and mp3s that are commonly used in daily life. With the enrichment of their functions, more stringent requirements are put forward for battery technology. The lack of existing battery technology leads to frequent charging, which greatly limits the use of such electrical appliances Ease of use
