报道称推出的 "Apple Watch Series 7"将具备监测血糖的能力，以确定血糖水平--通常不需要从患者身上亲自抽血。
A series of new patent applications backs up recent claims that Apple will introduce the ability for a future Apple Watch to monitor glucose using terahertz electromagnetic radiation without the need to draw blood.
Recent reports have claimed that the forthcoming "Apple Watch Series 7" will have the ability to monitor glucose to determine blood sugar levels — without the usual need to physically draw blood from a patient.
This is technology that very many medical companies have been pursuing, and it's one that Apple has previously researched over several years. Now, though, a series of four related new patent applications have been revealed, which together show Apple's latest proposal for such a system in Apple Watch.
None of the four mention the word glucose, nor the words "blood sugar." However, they all propose systems using absorption spectroscopy, which is what all non-invasive system proposals use for glucose monitoring.
"Terahertz Spectroscopy and Imaging in Dynamic Environments with Performance Enhancements Using Ambient Sensors," is the main new patent application, with the other three being related variations of it. All four are credited to chiefly the same team of inventors, and all are concerned with using an electromagnetic wave as part of the system.
