Journal of Diabetes Science and Technology · 2024

Key Findings

01The investigational glucose sensor demonstrated a mean absolute relative difference (MARD) of 14.5%, comparable to a commercial CGM (MARD of 13.9%).
02The lactate sensor showed 59.7% of readings within 20/20% and 83.1% within 40/40% of reference venous blood values.

Application

Design takeaway

Explore the integration of multiple physiological sensors into a single device to offer more comprehensive data and a better user experience.

How to apply

When designing wearable health trackers or medical monitoring devices, consider incorporating sensors for multiple biomarkers (e.g., glucose, lactate, hydration) into a single unit.

Project actions

01Consider how combining different sensors could make a product more useful or easier to use.
02Think about the trade-offs between accuracy and the number of sensors in a device.

Method & Evidence

AimTo assess the safety and functional accuracy of a novel, first-in-human, single-probe continuous sensor designed to measure both glucose and lactate levels.

MethodComparative clinical study

ProcedureParticipants had an investigational glucose/lactate multi-analyte sensor and a commercially available continuous glucose monitor (CGM) inserted. They underwent a meal challenge followed by an exercise challenge on days 1 and 4 of wear. Sensor readings were compared against venous blood samples analyzed for glucose and lactate.

ContextWearable health technology, medical device development, physiological monitoring

Variables

IVType of sensor (investigational glucose/lactate vs. commercial CGM), time of wear (Day 1 vs. Day 4), physiological challenge (meal vs. exercise).

DVMean Absolute Relative Difference (MARD) for glucose, percentage of readings within specific tolerances (e.g., 20/20%, 40/40%) for lactate.

CVParticipant physiology, ambient conditions, reference venous blood measurements.

Strengths & Limitations

Strengths

+First-in-human pilot study of a novel multi-analyte sensor.
+Comparison against a commercially available CGM and gold-standard venous blood measurements.

Limitations

The initial accuracy of the lactate sensor needs improvement, and the sensor's performance might vary during the initial wear period.

Reliability & validity

The study uses a comparative approach against established methods (venous blood, commercial CGM) to assess validity. Reliability is suggested by the improvement in MARD from day 1 to day 4, indicating a potential for sensor stabilization.

Think critically

How might the integration of glucose and lactate sensing impact the design of automated insulin delivery systems, and what are the potential ethical considerations of collecting such detailed physiological data?

Design Principles

"Multi-analyte sensing in a single device can enhance the utility and user-friendliness of health monitoring systems."

In the design of wearable health technology and medical devices, integrating multiple sensing capabilities into a single form factor can significantly improve user experience and data utility. This approach reduces the need for multiple devices, leading to more streamlined and potentially more effective health management systems.

What This Means for Your Design

A new sensor can measure both sugar and lactic acid in your body at the same time, which is better than just measuring sugar alone because it gives more information about your body's condition.
