摘要

A continuous daily-activity recording system called ldquolife microscoperdquo is developed. Acceleration waveform data is acquired without any data loss for a week with a 150-mAh battery. This is made possible by two novel techniques: ldquocool senserdquo and ldquosafe packetrdquo. Cool sense reduces power by 98% during continuous sensing at frequencies such as 20 Hz by using a millisecond time-scale sleep. Safe packet ensures lossless data acquisition with low-cost storage and efficient data compression in wireless environments with interference. In our experiment using the life microscope system, we recorded lossless activity data of 20 participants for more than 4 months.
