Product Details Implantable Activity and Temperature Bio-logger for Animals Overview of changes in animal activity over time. Minimally invasive, simple to implant and explant. On-board calculation of acceleration statistics from 3-axis accelerometer data. Ideal for use in physiological and behavioral research on animals. Key Features Statistical and raw 3-axis accelerometer data Minimally invasive Small, size 46mm x 15mm and 19g Long battery life – typically 3 years Stress-free long-term studies Description Statistical and raw 3-axis accelerometer data Each activity measurement is comprised of a burst activity measurement over one minute with a user programmable sampling frequency of 0.03Hz-10Hz. Statistical parameters are calculated on-board, based on the dynamic body acceleration of the animal. Raw accelerometer measurements can be stored in the logger’s memory for further processing. Minimally Invasive The DST centi-ACT is a bio-logger that simultaneously measures long term activity and core body temperature in the animal. The logger is simple to implant and explant and is made from ceramic housing to guarantee biocompatibility. Application This bio-logger is ideal for a variety of studies including those looking at behaviour, pre-clinical vaccine efficacy and stress response. It is suitable for use in laboratory, domestic and wildlife animal research. Overview of Changes in Animal Activity Over Time Measuring acceleration derived activity gives an overall view of changes in the study animals’ activity over time. The loggers measure acceleration in three dimensions, in relation to earth‘s gravity field. Each activity measurement is comprised of a burst activity measurement over one minute with a chosen sampling frequency of 0.03Hz-10Hz. Raw data can be stored in the logger’s memory. Stress-Free Long-Term Studies The activity logger has a battery life of over 19 months, when using a sampling interval of 10 minutes. The logger is especially useful when a comprehensive data set throughout the research period is needed with no disturbance to the animal. Since no data is transmitted there are no housing or environmental restrictions that apply to the data collection. Different Measurement Intervals Optionally, the loggers can be programmed with multiple different intervals within a study. This can, for example, be useful when different intervals are preferred during the day or night and can optimize battery life and save memory at the same time. Guaranteed accuracy and performance Every logger is individually calibrated for temperature and comes with a calibration certificate. In addition, a static calibration is performed on the acceleration values eliminating the need for the user to normalize the data. The loggers’ accuracy and performance are guaranteed for one year after purchase. Using the logger Simple in use, from setup to data retrieval Logger and accessories designed for ease of use throughout the research process Supported by Mercury software and a Communication Box (purchased separately) Programming the logger via Communication Box and software: set start time, date, and sampling interval On-board algorithm provides six statistical parameters for each one minute measurement: minimum, maximum and average EA* values, variance of EA, skewness and kurtosis. Raw accelerometer data can be stored for additional calculations. *EA stands for “external acceleration”, comparable to the vectoral sum of the dynamic body acceleration (VeDBA). Multiple measurement intervals can be set for the same study Software calculates memory capacity and battery consumption based on interval settings Data upload after logger recovery; results displayed in graphic and tabular form, exportable Logger can be sterilized and reused as long as the battery lasts Hermetically sealed, waterproof, high pressure tolerance; battery not replaceable Specifications SensorsActivity (3-axes acceleration), temperature Size (Diameter x Length)15mm x 46mm Housing MaterialAlumina (Ceramic) Weight (in Air/in Water)19g/12g Data Resolution12 bit (Temperature), 13 bit (Acceleration) Acceleration Resolution2 mg Temperature Range5°C to +45°C (41°F to 113°F)* Temperature Resolution0.032°C (0.058°F) Temperature Accuracy+/-0.2°C (0.36°F) Temperature Response TimeTime constant (63%) reached in 20 sec.
