Implantable Wireless Ultra-low Power Data Logger for Temperature Measurements in Animal Brains

Abstract:
This paper reports on the development of an implantable, microcontroller based, ultra-low power data logger for temperature gradient measurements in animal brains. In contrast to commercially available systems the device uses a wireless interface allowing the readout and reprogramming of the data logger after the implantation. To ensure low power consumption, a wake-up receiver is integrated in the system, aside a dedicated power management system, reducing the power consumption to 43 muW at one temperature sample/min/channel.
