Zimmer and Peacock sensors and electrodes can operate with the LMP91000 and a pre-designed board and design pack already exists utilizing the LMP91000; you can buy support from Zimmer and Peacock on how to implement the LMP91000 into your potentiostat see the buttons below.

Zimmer and Peacock's sensors are compatible with electronics based on the LMP91000.  Zimmer and Peacock have developed boards for our customers based on these electronics in order to drive our sensors.  The images above are of an early prototype board.


Our customers and collaborators are welcome to use the images able to help them design their own board independent of Zimmer and Peacock, or they can purchase a single board by using the button below, or they can contract with Zimmer and Peacock to consult on their electronics by clicking the button below.


Please note if you are designing your own board we do sell the connectors for the Zimmer and Peacock sensors, see the button below.

What is the performance/specification of your boards?

We are often asked 'what is the specification of your boards?' to which the reply is our board specification are based on the the LMP91000 chip.  The specification of the chip can be found on the TI website, please click the button below.  Zimmer and Peacock are unique in that we are both experienced in sensor development and the electronics necessary to drive and read these sensors.

Bluetooth connectivity

Zimmer and Peacock use the MSP430 on their standard boards, this can be swapped out with a Bluetooth equivalent.

How to set-up the LMP91000 for Zimmer and Peacock Glucose, Lactate and Oxygen Sensors



MODECN: 0x03 (three lead amperometric mode)

TIA: Whichever makes the best use of the ADC dynamic range. Try 0b00011011 (120 kOhm gain + 100 Ohm load)

REFCN: This is the hardest bit. Set zero selection to 20 % and bias polarity to positive. The ref source and bias percentage should be chosen to a configuration that makes the voltage close to 1.05 Volts for the glucose and lactate sensors. If you are not able to get this high, try running maximum (24 % and internal source). 


We would recommend experimenting with the glucose sensors since they are the most robust. And remember to store the sensors in a refridgerator.



MODECN: 0x03 (three lead amperometric mode)

TIA: These sensors give a higher signal than the glucose and lactate, so chose a step lower in gain settings. 

REFCN:  Set zero selection to 67 % and bias polarity to negative. The ref source and bias percentage should be chosen to a configuration that makes the voltage close to 0.5 Volts for the oxygen senors.



If you are using the LMP91000 chip and you want to extend the voltage applied ot the sensors beyond 0.5V then please change the input source to VREF DIVIDER by switching from VREF to VDD, this will allows you to get a a higher operating potential.
