Bluetooth low energy technologies for applications in health care: proximity and physiological signals monitors

Bluetooth Low Energy (BLE) is an exciting technology for health care applications. The big advantage over previous wireless technologies are its explicit low power design that allows deployment of such devices over many months or even years without the need to change batteries. This is especially critical in home health monitoring where compliance can often not be assumed. Here we describe the design of two Bluetooth Low Energy devices based on the BLE112 module from BlueGiga.
