Copyright © 2008 ICST. In this paper a new platform for monitoring of mobility in health care is presented. The platform was designed with a primary aim at monitoring of mobility and fall incidents in elderly people and is part of a wider system that uses web interfaces to gather data on several vital signs, mobility and fall events, and to communicate with the elderly people and warn family, health carers or emergency services if necessary. The fall and mobility sensing platform is based on measurements of the subject's accelerations in three degrees of freedom. Gathered data can be relayed to a mobile phone using a Bluetooth radio after which the information can be relayed to a web server. In this paper the design of the platform and tests with healthy subjects and with elderly subjects are discussed.
