Continuous Lactate Sensing


Problem statement

Problem Statement

  • Athletes need a means to non-invasively continuously monitor lactate anaerobic threshold for use in training

  • Current systems are expensive and cumbersome and require a laboratory environment


Performance criteria

Performance Criteria

  • Non-invasive

  • Low cost

  • Easy to use/simplistic

  • Continuous monitoring

  • Real-time feedback


Primary objective

Primary Objective

  • Continuous monitoring

    • Performance Evaluation

    • Training Exercises

  • Potential Users

    • Athletes & Professional Sports

      • 400,000 college athletes

    • Sport Enthusiasts

      • 467,000 marathon runners in U.S. 2009


Goals

Goals

  • Produce a novel method for monitoring lactate anaerobic threshold in exercise situations that is…

    • Hygienic

    • Easy to use

    • Noninvasive

    • Accurate

    • Inexpensive


Performance metrics

Performance Metrics

  • Lactate anaerobic threshold sensing

    • 1 mmol resolution

  • 80% users surveyed agree that device is

    • Comfortable

  • Less than 2 minute lag time

  • Less than $30 per unit

  • Reusable up to 10 times


Solution description

Solution Description

  • Sensor detects lactate levels in saliva

  • Lactate level transduced into electrical signal

  • Electrical signal triggers notification mechanism

  • Athlete modifies training accordingly


Design 1

Design 1

  • Saliva and blood lactate levels show high correlation

  • Embed microfluidic lactate sensor in mouth guard

sensor & processor


Design problem

Design Problem

  • Wires running from mouth guard would be cumbersome

  • Cost of microprocessor for wireless data collection is prohibitive

    • $150 – 800

Design 2

Design 2

  • Common mouth guard dimensions (7.5 cm × 7.5 cm × 2.5 cm )

  • Example saliva lactate sensor design (5.5mm×6.4mm×0.7mm)


Mouth guard architecture

Mouth Guard Architecture

  • Part of the mouth guard removed from where the chip and gel will be installed

  • Chamber for electro-sensitive gel and films connected to working electrode (red) and reference electrode (green)

  • Thin film of mouth guard material seals the chip and gel


Design problems

Design Problems

  • Modifying existing saliva lactate chip to better suit this application

  • Connecting Working Electrode and reference electrode to the gel chamber

  • Selection of electro-sensitive gel

  • Inherent variance of human lactate baseline and threshold


Future
