A system for remote communication of heartbeat; the system comprising: - a heartbeat sensor module attachable to a subject, the heartbeat sensor module having a heartbeat sensor operating to produce a signal representing the heartbeat of the subject and a wireless communication transmitter for communicating said heartbeat signal; - a host device located in proximity to the subject, the host device including a wireless communication receiver for receiving said heartbeat signal, and including data transfer means for communicating said signal over a data network; - a server connected to the data network to receive said signal and to communicate it to an authorised destination host device; - a destination host device connected to the data network to receive said signal when authorised; and - an output device for receiving said signal from the destination host device and producing a visual and/or audible representation of said heartbeat signal; - wherein the output device is configured for placement around a pillow or within a pillowcase and wherein the output device includes means for storing a unique ID and is configurable to be wirelessly paired with the destination host device, such that once paired, the destination host device will remember the unique ID and will automatically pair to the output device. - a heartbeat sensor module attachable to a subject, the heartbeat sensor module having a heartbeat sensor operating to produce a signal representing the heartbeat of the subject and a wireless communication transmitter for communicating said heartbeat signal; - a host device located in proximity to the subject, the host device including a wireless communication receiver for receiving said heartbeat signal, and including data transfer means for communicating said signal over a data network; - a server connected to the data network to receive said signal and to communicate it to an authorised destination host device; - a destination host device connected to the data network to receive said signal when authorised; and - an output device for receiving said signal from the destination host device and producing a visual and/or audible representation of said heartbeat signal; - wherein the output device is configured for placement around a pillow or within a pillowcase and wherein the output device includes means for storing a unique ID and is configurable to be wirelessly paired with the destination host device, such that once paired, the destination host device will remember the unique ID and will automatically pair to the output device. - a host device located in proximity to the subject, the host device including a wireless communication receiver for receiving said heartbeat signal, and including data transfer means for communicating said signal over a data network; - a server connected to the data network to receive said signal and to communicate it to an authorised destination host device; - a destination host device connected to the data network to receive said signal when authorised; and - an output device for receiving said signal from the destination host device and producing a visual and/or audible representation of said heartbeat signal; - wherein the output device is configured for placement around a pillow or within a pillowcase and wherein the output device includes means for storing a unique ID and is configurable to be wirelessly paired with the destination host device, such that once paired, the destination host device will remember the unique ID and will automatically pair to the output device.
