A flexible sensor applied to the back of the neck could A) monitoring football players with advanced devices
aid researchers in identifying concussions caused by B) dropping the dummy at precisely 60 centimetres
neck injuries in athletes. It is approximately the size of C) applying more than one patch on the neck and
a bandage and smoother and more precise than some monitoring them
current instruments. Football players are occasionally
D) analysing signals sent from a patch to a computer
monitored for concussions using bulky accelerometers
E) incorporating a wireless transmitter into the patch
mounted in their helmets. However, because the sensors
are not directly attached to the athletes’ bodies, they
are susceptible to false readings from sliding helmets.
The patch of a group of electrical engineers adheres
to the nape. It consists of two electrodes on a nearly
paper-thin piece of piezoelectric film, which produces
an electric charge when stretched or compressed.
The patch transmits electrical pulses to a computer
when the head and neck are moved. Researchers
can assess concussion-causing sudden movements
by analysing these signals. The patch was tested on
the neck of a human test dummy by dropping it from a
height of approximately 60 centimetres. Researchers
also equipped the head of the figure with various strain
sensors to establish a baseline level of neck strain. Over
ninety per cent of the time, they discovered data from the
patch aligned with data collected by the internal sensors.
The researchers are currently working on incorporating a
wireless transmitter into the patch to make it even more
compact.

A) To highlight the reasons behind a concussion
A) not only sends but also receives electrical pulses
