Data acquisition system for measurements in free moving subjects and its applications

Remo Lombardi; Giuseppe Coldani; Giovanni Danese; Roberto Gandolfi; Francesco Leporati

A low-cost, portable acquisition system for monitoring and processing human biomechanical parameters is presented. It is equipped with 16 input channels, each one linked to an external transducer by a suitable connector. Input signals from sensors are converted into a digital form by a 12-bit analog-to-digital converter and stored in a removable memory (memory card) respecting the PCMCIA standard interface, allowing the download of acquired data toward the host computer. The acquisition operating mode is programmable by a host PC, writing proper values into the memory card; then, the instrument acquires the defined number of channels at the selected sampling rate. The instrument is battery powered; then, it can be used in all those applications, like rehabilitation and sports medicine, where the freedom for subject movement is a constraint for the test. In fact, this instrument does not require an arranged environment for measurements, and it is not connected to a PC. Three sample applications are presented in which the instrument is used to evaluate human motor capability, physical parameters in amputees, and motor performance in athletes.

A Multi-Purpose Wireless Sensor Network Based on Zigbee Technology

Gian Mario Bertolotti; Giorgio Beltrami; Andrea Cristiani; Roberto Gandolfi; Remo Lombardi

Among a wide offer of wireless technologies, ZigBee is one of the most actractive for connecting low–volume devices, such as sensors. This paper aims at presenting a project which is being carried on at Microcomputers and Biomedical Devices laboratory (Department of Computer Science, Faculty of Engineering, University of Pavia, Italy). The goal of the project is the development of a prototype of ZigBee sensors network for temperature monitoring. The idea is to evaluate the capability of ZigBee technology in order to build wireless sensors networks for environmental monitoring. The use of a single chip which integrates a microcontroller and a ZigBee transceiver gives the possibility of developing wireless devices with small dimensions, low power consumption, and a good computing capability.

Gian Mario Bertolotti; Andrea Cristiani; Roberto Gandolfi; Remo Lombardi

A low cost portable acquisition system for monitoring and processing human body segment movements is presented It is equipped with 32 multiplexed input channels, each one linked to an external 2 axis MEMS accelerometer. Input signals from sensors are converted into a digital form by a 10 bit analog to digital converter and transmitted via Bluetooth technology to a remote PC. The instrument is battery powered and then it can be used in applications like ergonomics, rehabilitation and sport medicine. Labview 7.1 has been used to visualize in real time the human body segment movements

Portable acquisition system for measurements of pressures, temperatures and humidity in lower limb prosthesis

Giuseppe Coldani; Giovanni Danese; Roberto Gandolfi; P. Ghidetti; Francesco Leporati; Remo Lombardi

An instrument with a DSP for measurements of pressures, temperatures and humidity in lower limb prosthesis is presented. It has got sixteen analog input channels. The signals from the transducers are linked to the input channels and feed the conditioning network which is made up by amplification stages and peak detectors. Input signals are converted into a digital form by a 10 bit analog to digital converter integrated into the DSP and information are pre-processed and then stored in a removable memory with high capacity. The instalment is also equipped with an LCD display to show the progress of the interesting parameters in real time. Now we are testing the instrument at the Prosthetic Center in Vigorso di Budrio (Italy). The aim of these tests is checking the correct operation of the instrument in different working ways and bringing constructive modifications to prosthesis to better locate the sensors.

A Wireless Sensors System for Sport Studies

Gian Mario Bertolotti; Giorgio Beltrami; Andrea Cristiani; Roberto Gandolfi; Remo Lombardi

A system based on wireless sensors for biomechanical and sport applications is presented. It is currently used to study the interaction between athletes and sport surfaces, such as soccer turves and athletic tracks, with special focus on ankle vibrations. Thanks to a Bluetooth connection, the wireless sensors can communicate with a PC, where data are visualized and elaborated in real time. Thus, the subject under test can move freely, since there are no cable constraints.
