As wearable technologies have only become accessible to most
people in the last couple of years, the majority of current assistive
and telehealth systems are constructed based on ambient sensors.
The high installation cost and the lack of ability to collect and store
information have hindered the use of ambient sensors for home
care applications until recently. The emergence of the Zigbee and
Z-Wave standards has enabled the wide adoption of low-cost wireless
sensing systems for home care. For instance, the Connecting
Assistive Solutions to Aspirations, an Innovate U.K.-funded project,
demonstrated the feasibility of using low-cost Z-Wave sensors
to construct a home care system for long-term care application
