| abstract |
A monitoring device to be applied to an object for monitoring a condition of the object includes a housing configured and dimensioned for application to the object; a sensor within the housing for sensing the condition to be monitored and for producing an electrical output corresponding to the sensed condition; and an electrical power generator within the housing for receiving energy from a source externally of the housing and for generating, from the received energy, electrical power for energizing the sensor. The monitoring device is particularly useful for monitoring a physiological condition of a living subject, e.g. by implanting the monitoring device, swallowing it or attaching it to the external skin of the subject. |
