In this demo, we present a novel rapid prototyping platform
called SenStick2, which is all-in-one sensor with wireless
charging. The main purpose of our platform is to sensorize
our personal belongings easily and smartly for recognizing
our living activities. The size of SenStick2 hardware (board)
is 50mm(W) 10mm(H) 5mm(D) and its weight is around 3
(g) including a battery. On this tiny board, 8 sensors (acceleration,
gyro, magnetic, light, UV, temperature, humidity,
and pressure), flash memory, BLE, and battery are embedded
in high density. The battery life in stand-alone mode is
more than 15 hours. For SenStick platform, we have developed
the support software for iOS and Android OS. It can
monitor the sensing data and also record the ground truth
video simultaneously and synchronously. Furthermore, 3D
CAD data of various case designs will be open for users in
SenStick community site. By providing 3D case data, all the
researcher can measure every tiny activities in a daily life
easily and smartly.
