Abstract
The disclosed invention provides sweat sensing devices with smart sweat stimulation and sensing embodiments: which improve the dependability and predictability of sweat sampling rates; achieve a desired number of sweat sampling events per day while minimizing skin irritation and prolonging device lifespan; and use physical, optical or thermal sweat stimulation to augment or replace chemical sweat stimulation.
Claims8
A method of measuring at least one analyte in sweat with a sweat sensing device, comprising:
- applying a sweat sensing device to a wearer's skin;
- scheduling a plurality of sweat sampling events that are required for an application;
- measuring a sweat generation rate from the wearer's skin;
- determining a sweat onset temperature;
- stimulating sweat if the sweat generation rate is insufficient to provide each of the plurality of sweat sampling events with a sweat sample having a chronological assurance;
- and
- taking a plurality of sweat analyte readings.
