Method of Linné

The Method of Linné (MoL) is trademarked, has been patented in Sweden, China and the US and pending applications in Europe and Canada.

MoL is a mobile eHealth solution that minimizes losses in production and ensures storage (documentation), analysis, real time results and validity of data. The method shows information rapidly and in a pedagogical manner and is scientifically structured. Measurement of heat loss and recovery is carried out under controlled conditions in terms of what people did before the test, test conditions and test procedures. MoL measures the periphery blood circulation in hands and feet with help of a thermal camera and a software program on a laptop. Immediately after the measurements are finished, the data are sent to a database where they are stored, analyzed and presented in a predefined health report that medical personnel can open, comment on, make recommendations, and return to the test unit, as shown in the figure below.


The test unit includes a cold screen to scan the body parts to be measured and a cooling bath.

Method of Linné -measurement how it works

How the measurements are performed

  • Rest for 30 min in + 20° C without touching cold or warm surfaces. 
  • Data and answers on blood pressure, pulse, body temperature, room temperature etc. are noted in the measurement program. Note: we ALWAYS HAVE A WRITTEN AGREEMENT – if it’s going to be stored in the data base, it does not have the personnel number of the test individual.
  • The measurement data suggest an individual code for the person to be tested. The code can be used by the person, if he/she wants to be retested to see if there has been any change.
  • Take measurements of the baseline temperature (initial temperature).
  • Cool the hands or feet in cold water.
  • Measure the recovery process as average temperature in predefined zones every 10 seconds for at least 5 minutes.
  • Send the data to a database that stores, analyses and delivers data/decision support (in real time) to a medical doctor who can comment and/or add medical recommendations, convert the health report, and send it back to the measurement computer.
MoL can measure the effects of using vibrating tools, drugs, tobacco. It can also be used in product development, e.g. to evaluate new designs for glows or personal protective equipment.
