教学资源 校本课程1. Feels like it’s real

1. Feels like it’s real

The COVID-19 pandemic has made people more concerned about physical contact. Social distancing rules force us to stop hugging and shaking hands. Is it possible for us to feel the sense of touch without actually touching anything? Researchers are trying to make this happen.

According to Science News, our body’s sense of touch is complex. Every time we touch something, nerve receptors (神经受体) receive signals about texture (质地), temperature and more. These signals tell our brain if something is smooth or rough, wet or dry. 

The goal for haptic (触觉的) scientists is to mimic (模拟) touch sensations. For example, John Rogers and his team from Northwestern University, US, have developed touch patches that can stick to people’s skin. The patches vibrate (震动) when they receive signals, giving people the feeling of stroking or tapping something.

This skin patch can be used in telemedicine (远程医疗) in the future, according to Rogers. It can store data that is collected from a patient’s body. Then the data will be translated into sensations. When doctors distantly receive these sensations, they can feel like they are touching the patient’s body with their hands. 

People with prostheses (假肢) could also benefit from this. In one study, researchers from University of Chicago, US, built sensors into bionic (仿生的) hands. Three people who had lost a hand tested the bionic hands. They felt a sensation of touch when the thumb was touched. 

Some researchers are also working on computer screens that can mimic different textures. “Ideally, in the long run, if you’re shopping online, you could feel fabric (织物),” said Cynthia Hipwell, a mechanical engineer at Texas A&M University, US.
