Haptic Rotary Encoder
Control of a heart-lung machine
Task: Development of an encoder with a defined operating torque
Customer: Angst+Pfister Sensors and Power
Angst+Pfister Sensors and Power (formerly Pewatron AG) specialises in high-quality sensors and power supply solutions. Their products are used in many different areas of industry. These include medical engineering, wind energy and photovoltaics.
joylab develops customised sensor solutions for Angst+Pfister Sensors and Power. One of the projects included the development of an optical encoder, which is used as a control knob to set the parameters of a heart-lung machine; for this, the encoder must meet very strict haptic requirements. The sensor is characterised by defined static and sliding friction torques as well as its long service life.
