Sensor Technologies

Sensor technology is central to my hardware design experience. Optoelectronic sensing, in particular, is one of the areas I most enjoy working on. I have developed electronic circuits for industrial and defence applications using sensors based on different detection principles.

  • Optoelectronic sensing: Detection circuits using infrared LEDs, photodiodes, and phototransistors, as well as optical detectors sensitive to specific spectral bands for flame-detection applications. (Mavili Elektronik, Teknim Elektronik, Fenac Encoders & Sensors, Inovenso)
  • MEMS-based sensing: Integration of MEMS sensors for acceleration and tilt measurement into electronic designs. (Fenac Encoders & Sensors)
  • Optical encoders: Optical detectors and associated readout circuits used to obtain position and motion information. (Fenac Encoders & Sensors)
  • Magnetic sensing: Circuit development using magnetic sensors selected according to the requirements of industrial and defence applications. (Fenac Encoders & Sensors)

Hardware Design Areas

My strongest hardware design experience is in circuits for reading and processing low-level sensor signals. I have developed sensor readout and signal-conditioning circuits by addressing high gain, low noise, and low power consumption together.

  • Sensor readout and analog signal conditioning: Amplification, filtering, and conditioning of low-level sensor signals for reliable measurement and processing. (Mavili Elektronik, Teknim Elektronik, Fenac Encoders & Sensors, Inovenso)
  • Low-power circuits: Circuit design focused on reducing power consumption while maintaining measurement performance and meeting operating requirements. (Mavili Elektronik, Teknim Elektronik, Fenac Encoders & Sensors, Inovenso)
  • Power electronics: Design of switched-mode power-supply boards with output currents below 10 A. (Fenac Encoders & Sensors)
  • Mixed-signal hardware: Microcontroller-based boards combining analog measurement circuitry, digital control, and multiple communication interfaces. (Mavili Elektronik, Teknim Elektronik, Fenac Encoders & Sensors, Inovenso)
