| Research Abstract |
In 2008 I developed WB-3, a very compact and lightweight Inertial Measurement Unit (size 26×20×8mm and weight 2.9g).
During 2009, WB-3 was applied in a vast range of applications, such as: performance measurement and assessment for laparoscopy skill analysis, both on the surgeons and on the tools; performance measurement and assessment for neurosurgery; mastication analysis; gait analysis for healthy and disabled persons. All the applications were successful (for the details see the published literature), but the results pointed out the need for a more compact sensing unit, together with the wireless capability.
Therefore in 2009 I also developed a new IMU, named WB-4. WB-4 integrates the following components in a 20×17mm board (2.0 grams weight): 16 bit 3 Axis accelerometer LYS331DLH; 12 bit 3-axis Gyroscope LYPR540LH; 12 bit 3-axis Magnetometer HMC5843; STM32F103CB 32bit microcontroller for embedded signal elaboration and data exchange.
A complete wireless solution can be obtained by adding the commercial Bluetooth communication board ZEAL-C01 and the Li-Ion battery KAIO 501717 (80 mAh). The resulting system is enclosed in a case of 20×17×7mm, and weights about 6.0 grams (this is about 10 times smaller than any other commercially available system). WB-4 can reach 100Hz continuous data exchange up to 10 meters and with an autonomy up to 1 hour
