At electronica 2016 we will, among others, demonstrate the Bluetooth Low Energy sensor BlueTEG with thermoelectric energy supply. BlueTEG measures sensor readings such as the ambient temperature or acceleration rates and transmits this data via Bluetooth to a smartphone or tablet PCIntegrated in a compact housing, BlueTEG uses the temperature difference between the warm or cold pipes and the environment to produce electrical energy to supply the electronic systems. BlueTEG does not require a battery and can be used in all areas of structure monitoring, wearable sensors or wireless sensor systems. See at the electronica how efficiently energy can be gained from temperature differences.
For the monitoring of larger battery storages, we are showing the flexible battery management system FlexBMS. A small electronics module at each cell detects cell parameters such as voltage and temperature. Optimized bus communication between these electronic modules minimizes the need for wiring between the cells. The FlexBMS is also capable of precisely predicting the remaining capacity and the state-of-health by means of shunt- or resistance-based current measurements. This allows run time or range forecasts to be made, which eliminates the need for a safety buffer. The monitoring of any cell or module combination of battery cells does not require any hardware adaptation. Furthermore, this flexible BMS can actively compensate for charge differences between the individual battery cells in order to always utilize the maximum capacity of the battery cells.
RFicient® is the solution for wireless applications that are designed to provide an operating life of several years with a minimal amount of maintenance. The ultra-low power (ULP) receiver technology RFicient® enables 24/7 monitoring of wireless sensor networks in multiple frequency bands. The current consumption below 3 µA and the operation without a microcontroller make a service life of your mobile applications of up to ten years possible. The particularly fast response capability in the order of milliseconds also enables real-time applications. Consequently, this novel and efficient RF solution is predestined for the Internet of Things.
Wearable electronics capture ambient information and physiological data for monitoring health and training activities while consuming minimal energy. This approach utilizes low-power electronics, which contain special sensors and signal / data processing technology, in combination with medical and sports science models.
In this interdisciplinary project, researchers are demonstrating the use of inductive power transfer technology in an electronic ball bearing by incorporating expertise from the fields of power electronics and inductive transfer, data interfaces, servo loops and electromechanical robustness analyses.
Large-area distributable sensors, addressing and evaluation circuitry, small TFT power drivers and control circuitry are the building blocks that lead to novel integrated thin-film systems for energy, automotive, industrial, consumer, and lighting applications. Thin-film electronics offer ultrathin form factor, mechanical flexibility, large-area coverage and the prospect of employing low-cost fabrication techniques like printing or roll-to-roll processing.
