OptoForce is a university spin-off company from Budapest, creating multi-axis silicone force sensors. In the sensors infra-red light is used to detect the deformation of the silicone sensor structure, which is a radically new and unique approach. OptoForce supplies its sensors to high-tech research labs and companies in the areas of robotics, neurorehabilitation, medical analysis and industrial automation in North America and Europe.
The two founders of OptoForce worked together on a walking robot, where they faced constant issues with the weight, the rigidity and the cost of the available multi-axis force sensors and so they decided to develop their own solution - which became the first prototype of their current sensors.
All our force sensors use infra-red light to detect deflection in the silicone structure of the sensors. In the middle of the sensors we have an LED, surrounded by 4 photo-diodes, covered with transparent, reflective and covering layers of silicone. By calculating differences between the amounts of light on the different diodes, we can reconstruct the acting force in 3 axes with high precision. Our 7mm tall sensors are now used in the fingers of adaptive grippers, while our bigger sensors are used as 3- and 6-axis load cells.
extremely high native safe overload range (up to 600% without additional protection)
the compliant silicone structure is ideal for force control and human-machine interaction
