Smallest, thinnest, lightest 3 dimensional axis tactile sensor based on MEMS technology

SchokacChip™ is the tactile sensor with small-high sensitivity based on MEMS technology.
Realizing high sensitivity for 3 dimensional axis by processing 3 piezoelectric elements and locating them at 3 dimensional axis on the 2mm² chip.

Needs and Markets for ShokacChip™

Because the conventional tactile sensors mainly detect the pressure, additional step such as calculation of output changes between sensors is necessary to detect the shear stress.
ShokacChip™ can detect shear stress directly as one sensor. You can implement ShokacChip™ not only on the flat surface but also curved surface due to its small and thin body. The density of implemented sensors can be easily changed. Additionally, it is possible to adjust the sensitivity and feel by changing the material of exterior covering silicon chip.
With regard to the market of ShokacChip™, the gripping and tracing movement at Robot hand, which could be significantly improved by tactile sensor, is one of the best markets for ShokacChip™.
As the other examples, human machine interface at gaming and smart phone, sports simulation by embedded it into shoes, and even anti-slipping system at automotive might be realized by embedded it into tires to measure the friction force.
