Product Overview

What is Shokac Chip™

Shokac Chip is one of the world's smallest tactile sensors capable of measuring all six axes of force and torque. By leveraging our proprietary ultra-miniature MEMS^* technology and advanced material processing expertise, it can simultaneously detect three-axis forces (Fx, Fy, Fz) and three-axis moments (Mx, My, Mz).
Its compact and ultra-thin design provides exceptional integration flexibility, while its highly accurate 6-axis sensing capability enables reliable performance across a wide range of applications and operating environments.

Micro Electro Mechanical Systems

Structure and Principle

The sensor incorporates a MEMS chip, a semiconductor-based sensing element, enabling high-volume manufacturability and scalability. By combining MEMS technology with our advanced material processing techniques, the sensor achieves outstanding performance in an extremely compact form factor, including a low noise level of approximately 0.2 N (Fz) and high measurement accuracy.

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 contact position detection. 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 contact position detection. It becomes possible to grasp small and fragile items.

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

Material Evaluation / Tactile Evaluation

(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."
