   保專家認為
，多用傳感器解決了創新中的若幹問題。例如

，除將磁能轉換為電能外
，處在磁場中的傳感器上還會產生那些過程；傳感器上還會有那些機械程序存在；能否在處理輸出信號時獲得諸如壓力、溫度、光guang照zhao等deng一yi些xie非fei電dian信xin參can數shu等deng。新xin研yan製zhi的de集ji成cheng矽gui多duo用yong傳chuan感gan器qi可ke以yi同tong時shi並bing獨du立li地di對dui外wai磁ci場chang強qiang度du和he方fang向xiang及ji環huan境jing溫wen度du進jin行xing測ce量liang。保bao專zhuan家jia稱cheng，在zai當dang前qian的de監jian測ce技ji術shu領ling域yu還hai沒mei有you類lei似si的de多duo用yong傳chuan感gan器qi
