Summary
This sensor lasts the longest - 180 days. It has to be placed under the skin by a healthcare provider. It has two parts, the implantable sensor and a transmitter that sends data to a mobile device.
MARD: 8.5-9.1%
*Recently FDA approved for use with insulin pumps.
Connected smart caps that recommend insulin doses for people using multiple daily injections. This system combines the FreeStyle Libre 2 CGM with insulin pen smart caps to provide daily dose recommendations.
Participating in the Bigfoot Unity program requires an agreement between Bigfoot Biomedical and the health care provider. After establishing a contract, the prescribed Bigfoot supplies are delivered in a "one-stop-shop" directly to the patient's door each month. Information about the Bigfoot Unity program can be found on the Bigfoot Biomedical website.
Components

Eversense : Sensor
Professionally inserted by a physician during a medical visit. Minor procedure.

Eversense : Transmitter
Transmitter sits outside of the body and is held on by an adhesive. Sends data every 5 minutes to a connected mobile device.

Eversense : Receiver
Real-time glucose measurements sent to a compatible mobile-device or smart watch. No need for a separate receiver. Available for both iOS and Android devices.

Bigfoot Unity : Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every minute.

Bigfoot Unity : Controller
Smart cap displays dosing recommendations for manual insulin delivery through multiple daily injections.

Bigfoot Unity : Receiver
Smartcap is used to scan the sensor and displays dosage information directly on the screen and smart mobile device.

Patient Considerations
Active Lifestyle
Water-resistant transmitter when submerged in 1 meter of water for up to 30 minutes and must be within 25 feet of the connected smart device.
Light on body. Pens are easy to use and do not remain attached to the body, senor is light on the body.
Avoiding Highs and Lows
On-body vibration alerts when blood glucose levels are higher or lower than the set range. Trend arrows show the direction glucose is heading, with the rate of change.
Limited customizability. System integrates the FreeStyle Libre 2 CGM for high/low alerts but requires manual dose adjustment and limits the ability to adjust basal insulin throughout the day.
Comfort
Longest lasting sensor fits comfortably under the skin. Minor procedure is required.
Many components. Have to carry pens, smart caps, pen needles, and CGM is attached to the body.
Easy Insulin Dosing
Predictive alerts make insulin dosing easier by tracking high and low trends.
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
Easy to Use
Minor procedure. Requires insertion by a physician during a medical visit.
Simple design. One-button device with easy to read display.
Fewer Fingersticks
2 daily finger-sticks are needed to calibrate the sensor.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Somewhat discreet. Tiny sensor is implanted under the skin, so the user can be discreet when needed. Ability to see sugar on watch or phone. Sensor not movable on body and requires regular meter use.
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. Sensor is the smallest option available.
