Scientists have developed a smart textile vest capable
of monitoring body temperature and identifying early
signs of hypothermia in elderly individuals. The innova
tion is designed to address the higher risk older people
face due to faster body heat loss, reduced temperature
regulation, chronic illnesses, medication effects and
general frailty.The research, led by Dr Theo Hughes-Riley
from Nottingham Trent University’s Advanced Textiles Re
search Group (ATRG), focuses on four miniature thermis
tors integrated directly into the vest’s yarns. These sensors
continuously track changes in body temperature.
Each thermistor measures just 1mm in length and 0.5mm
in width. They connect to a microcontroller via Bluetooth,
enabling real-time temperature data to be sent to a
smartphone or other device. The system can trigger
alerts if abnormal temperature readings continue over a
period of time. To ensure durability, the thermistors are
sealed in resin for full washability and protected with a polyester braid. They are strategically positioned at key
body points, two on the chest and two on the scapula,
and are designed to remain imperceptible to the
wearer.The prototype has been tested during common
daily activities including sitting, walking, jumping and
reaching, confirming that the vest performs reliably in
real-life conditions. Trial data showed distinct
temperature variation patterns that may help detect
abnormal physiological responses before they become
critical.
Dr Hughes-Riley from the Nottingham School of Art and
Design noted that hypothermia is particularly dangerous
for elderly individuals, especially those living alone
without immediate support. He explained that
integrating electronic textiles into an everyday garment
like a vest could enable carers and healthcare
professionals to respond quickly to potential risks and
provide timely assistance.
