Sensor for measuring the activity of beta-pancreatic cells or of islets of langerhans, manufacture and use of such a sensor
First Claim
1. A sensor including:
- microelectrodes which are configured to dynamically measure in real time and continuously, electrical signals produced by all cells types in islets of Langerhans in culture disposed on the microelectrodes during their physiological activation, wherein the sensor also includes at least one set of processing units, in which each processing unit is coupled to a corresponding one of said microelectrodes and;
each processing unit is configured to process the electrical signals measured by said corresponding one of said microelectrodes and extract at least one parameter from said processed electrical signals indicating a need for insulin by a patient, in real time and continuously.

Abstract
The invention relates to a sensor (2) including: a microelectrode assembly (21); and β-pancreatic cells (23) or islets (230) of Langerhans in culture on the microelectrode assembly (21); characterized in that the microelectrode assembly (21) is designed to measure dynamically, continuously and in real time, electrical signals (V) produced by the β-pancreatic cells (23) or the islets of Langerhans (230) upon physiological activation. The invention also relates to the field of devices that can be implantable in the body of a patient, and including an insulin dispenser for dispensing an amount of insulin. The invention also relates to a method for manufacturing such a sensor and to such a device and a use of such a sensor.
