摔倒是导致老人受伤的最主要因素,美国每年就有超过2万人因此丧命。现在,一组研究人员正利用与智能手机触摸屏相同的技术应对老人跌倒,确保一旦发生事故能立刻探测到。为了完成该项目,研究者在电容式传感器中加入狭长且柔韧的填充材料薄板。当有行人走过或在附近坐下时,传感器能够立刻探测到,就算隔着一层楼也毫无影响。探测器获取的信息将通过无线方式传送到一台电脑
Fall is the leading cause of injuries to the elderly. In the United States, more than 20,000 people die each year. Now, a team of researchers is using the same technology as a smartphone touchscreen to cope with falls, ensuring immediate detection in the event of an accident. To complete the project, researchers added thin, flexible sheets of filler material to capacitive sensors. When pedestrians walk or sit down nearby, the sensor can detect it immediately, even if it is separated by a floor. The information obtained by the detector will be wirelessly transmitted to a computer
