Project introduction:

The company is a German deep-tech start-up, headquartered in Bochum, Germany. Its technology originated from years of research and accumulation by Ruhr University in Bochum and Ilmenau University of Technology. Its core innovation is to replace the traditional electronic sensing scheme with a pure micro-mechanical architecture, and realize the real "passive wireless sensing".

Passive Strain Sensor:

● Based on MEMS technology, mechanical integrated circuit architecture is adopted; Instead of microelectronic components, pure micromechanical components are used to realize the sensing function.

● Wireless reading by RFID (Radio Frequency Identification) without wired connection.

● Zero energy consumption operation: no external power supply or battery is needed for measurement and storage.

● Mechanical memory function: even if there is no continuous power supply, it can detect overload and save the limit value.

● Direct digital output: The sensor chip directly outputs the digital strain value without additional electronic components.

● High integration: All functions are integrated on a single silicon chip.

Subversive passive technology architecture completely solves the power supply problem of traditional wireless sensors and eliminates the maintenance cost of battery replacement; Peripheral devices such as signal conditioning circuit, ADC converter and data memory are omitted; Pure machinery solves the aging problem of electronic components, which is more stable in extreme environment (high temperature resistance and electromagnetic interference resistance).

This technology is of great significance for industrial scenes (such as offshore wind power, aviation structures and long-span bridges) that are difficult to supply power or maintain.

At present, the company is in the early stage of commercialization, has received multiple support from the German Federation and North Rhine-Westphalia, and its technical maturity has improved rapidly. It has carried out proof-of-concept projects with many industrial partners and is expected to enter the large-scale market stage this year.
