A 
system for long-term remote medical monitoring is especially suitable for the medical supervision of astronauts onboard a space 
station. The 
system includes at least one autonomous sensor unit (SU) with a sensor (1) and transmit / receive electrodes (2) connected to a microchip (3) and mounted on a carrier (4) in the form of an 
adhesive bandage that can easily be applied to the 
skin of the subject astronaut (11). The 
system further includes a body 
transceiver (10) that is worn on the body of the subject and acts as a centralized transmitting and receiving unit, and a portable 
data logger (12). Medical data such as the 
pulse rate and the like, as well as 
environmental data such as the ambient surrounding 
air temperature, are sensed by respective allocated sensor units (SU) and transmitted from the sensor units as electrical signals via the 
skin and other body tissues of the subject (11) to the body 
transceiver (10). From the body 
transceiver (10), the data signals are further transmitted, for example by a radio or 
infrared transmission, to the 
data logger (12), where the data can be recorded, displayed, processed, or further transmitted via a 
satellite (14) to a 
base station (13) or a ground-based facility such as a hospital (15). 
Polling signals are also transmitted from the body transceiver (10) to the sensor units (SU) in a 
wireless manner through the 
skin and other body tissues of the subject.
