人們在處理傷口的時候，難免會因碰及傷口而造成疼痛。新型智能繃帶可以防止這種情況的發(fā)生，給傷者帶來福音。

How?can?doctors?make?sure?a?dressed?wound?is?healing?without?taking?off?the?ban?dage？?This?is?a?difficult?problem，?because?removing?a?bandage?can?damage?the?healing?process.?Technology?presented?in?a?new?study?could?help.

This?new?smart?bandage?contains?a?sensor?that?can?sensitively?measure?wound?mois?ture?levels?and?then?transmit?the?data?to?a?nearby?smartphone，?without?requiring?doctors?to?remove?the?bandage.?By?changing?the?geometry?and?materials?in?the?bandage，?users?may?be?able?to?adjust?it?to?suit?different?types?of?wounds.?The?technology?could?help?doc?tors?to?monitor?wounds?more?easily?and?successfully.

Chronic?wounds?can?be?a?source?of?significant?suffering?and?disability?for?patients?who?experience?them.?Getting?such?wounds?to?heal?is?tricky?and?there?are?many?factors?that?can?affect?wound?healing.?However，?one?of?the?most?important?is?moisture?levels.?If?the?wound?is?too?dry，?the?tissue?can?become?dry;?if?the?wound?is?too?wet，?it?can?become?white?and?wrinkly.?However，?if?a?doctor?wants?to?check?the?moisture?levels?of?a?wound，?then?he?or?she?needs?to?remove?the?bandage，?potentially?damaging?the?delicate?healing?tissue.?These?issues?have?inspired?this?latest?smart?bandage.

The?choice?of?materials?was?a?challenge，?so?researchers?applied?a?special?material?onto?a?gauze（紗布）?using?a?technique?called?screen?printing，?and?then?connected?the?gauze?with?commercially?available?bandage?materials.?The?idea?is?that?changes?in?the?moisture?levels?of?the?wound?cause?a?change?in?an?electronic?signal?measured?by?the?sen?sor.

To?test?their?bandages，?the?researchers?exposed?them?to?artificial?wound?liquid，?and?also?tested?different?bandage?materials?and?shapes.?They?found?that?the?bandage?was?highly?sensitive，?providing?different?readings?in?different?conditions，?suggesting?it?could?be?a?valuable?tool?in?wound?management.

“We?developed?a?range?of?bandages?with?various?layers?and?different?absorption?properties?and?characteristics，”?said?Dr?Luca?Possanzini，?one?of?the?researchers.?“The?idea?is?that?each?type?of?wound?could?have?its?own?appropriate?dressing.?However，?we?will?need?to?further?perfect?the?sensor?geometry?and?determine?the?appropriate?sensor?values?for?the?best?healing?before?we?can?apply?our?technology?to?various?types?of?wounds.”

Difficult?sentences?in?the?text

1.?However，?if?a?doctor?wants?to?check?the?moisture?levels?of?a?wound，?then?he?or?she?needs?to?remove?the?bandage，?potentially?damaging?the?delicate?healing?tissue.?然而，如果醫(yī)生想檢查傷口的濕度，他們就需要取下繃帶，這可能會破壞脆弱的愈合組織。

【點石成金】句中if?a?doctor?wants?to?check?the?moisture?levels?of?a?wound為if引導的條件狀語從句，potentially?damaging?the?delicate?healing?tissue為結果狀語。

2.?The?idea?is?that?changes?in?the?moisture?levels?of?the?wound?cause?a?change?in?an?electronic?signal?measured?by?the?sensor.?其原理是，傷口濕度的變化會引起傳感器測量到的電子信號的變化。

【點石成金】句中that引導表語從句，that在從句中不作成分，沒有實際含義，但不能省略;measured?by?the?sensor為修飾signal的后置定語。
