Product Overview
What is Shokac Chip™
Centered on proprietary MEMS* technology and material processing technology, this is the world's smallest haptic sensor with millimeter-level ultra-small chips, capable of simultaneously acquiring six-axis data for FX, FY, FZ, MX, MY, and MZ.
Because multidimensional data can be obtained locally, it is suitable for complex environments where situational judgment with 3D data (Fx, Fy, Fz) is difficult, or when more representations are needed.
It is also possible to estimate the surrounding force distribution from a single measurement point. This enables advanced sensing without the need for expensive multi-point measurement sensors.
Micro Electro Mechanical Systems

Structure and Principle
The sensor core uses a high-precision MEMS chip manufactured using an 8-inch wafer process. By combining semiconductor manufacturing technology with material processing technology, we achieved an extremely low noise level of about 0.02N and high reproducibility. It boasts high durability, passing over one million press tests, and can handle a wide range of phases from research and development to mass production products.

Performance comparison with
other tactile sensors *
Tactile sensors each have their own strengths and limitations depending on the sensing principle employed. Optical (Vision-based) sensors are well suited for distributed sensing, but they are constrained in terms of durability, thickness reduction, and sampling rate. Magnetic-based sensors offer excellent durability and distributed sensing capabilities; however, challenges remain regarding noise immunity and measurement repeatability. Multi-axis force sensors from other manufacturers can provide high accuracy and rated load capacity, but their relatively thick structures limit the range of applications.
SEKISUI CHEMICAL's Shokac Chip™ (MEMS) does not focus on excelling in only one specific characteristic. Instead, it is designed to achieve a balanced level of performance across all seven key attributes: durability, thinness, repeatability, rated load, noise resistance, sampling rate, and distributed sensing capability. Please select the sensing technology that best matches the priorities of your intended application.

According to our research
Applications

- (1) Robot/Humanoid
- Improved stability of object grip. Gripping force and contact strength are detected through distribution measurement. It becomes possible to grasp small and fragile items.

- (2) Controller
- Enables delicate and complex operations.
Detects combined input from sticks, buttons, and triggers.

- (3) Material Evaluation / Tactile Evaluation
- It enables quantitative measurement of material softness, texture, and tactile characteristics.
Do you have any of these concerns?
- Breaks quickly even after installation: You want delicate work but worry about the durability of the sensor itself.
- Unprofitable: If you place multiple or multiple sensors costing tens of thousands of yen each, the price of the end product will skyrocket.
- Too large in size: Sensors cannot be implemented within structural constraints.
- Insufficient data volume: 3-axis sensors cannot fully capture complex "slip" and "torque."
