Introduction to Surface Pressure Sensors (Large Sheet Pressure Sensors)

It is a sheet-type pressure-sensitive sensor. It can sense the pressure distribution across the entire surface. Customization to meet customer specifications is also possible.

We have developed an ultra-thin load sensor of a film laminated type that detects changes in electrical resistance based on the magnitude of the load applied to the pressure-sensitive area. Due to its PET film laminated structure, the sensor is ultra-thin (around 0.5 mm) and offers resistance value output. We can accommodate prototype to mass production based on your desired size, shape, performance, surface processing, and printed design according to your applications and purposes. It is also possible to provide a kit for a "buzzer sound and LED lighting unit" that can be used independently, as well as devices that wirelessly transmit sensing output via Bluetooth. The sensor can detect the degree of load or impact at various points and surfaces. 【Features】 - We can accommodate prototype to mass production based on your desired size, shape, performance, surface processing, and printed design according to your applications and purposes. - Specifications can be modified to detect loads above a specified threshold (for surface application). - Waterproof and dirt-resistant products are also available. *For more details, please refer to the PDF document or feel free to contact us.

Waterproof and dirt-resistant manufacturing is also possible! Ultra-thin load sensor with stainless steel laminated type.

We have developed a small and inexpensive sensor capable of detecting approximate loads. The sensor is fixed with screws at three points around the outer circumference of the case (with a base), and it comes with a push rod, cover, and base, allowing for immediate load detection. It has a resolution of 1/25 (maximum detection load ratio), excellent load resistance, and minimal creep and hysteresis. 【Features】 ■ Comes with a push rod, cover, and base for immediate load detection ■ Fixed with screws at three points around the outer circumference of the sensor case (with a base) ■ Resolution of 1/25 (maximum detection load ratio), excellent load resistance, and minimal creep and hysteresis ■ Available in a series of six models with maximum detection loads of 100gf, 500gf, 1kgf, 2kgf, 5kgf, and 10kgf *For more details, please refer to the PDF document or feel free to contact us.

When measuring height, it can be positioned vertically to detect the height! Because it is sheet-like, it can also be used on curved surfaces.

We have developed a "Slide Sensor" of the measuring type that can detect the position touched. It is capable of one-axis detection as well as two-axis (XY) detection. With a simple and durable structure, it achieves high-speed response. It can be used when moving operating tables to arbitrary positions or identifying moved positions, as well as for measuring height. Please feel free to contact us when you need assistance. 【Features】 ■ Sheet-type volume & switch ■ Resistance value changes by sliding the sheet surface ■ Can turn ON/OFF with a light touch on the surface ■ Equipped with a switch function (ON, OFF) in addition to position detection ■ RoHS compliant *For more details, please refer to the PDF document or feel free to contact us.

Difficult-to-measure objects can be detected in several stages! We will develop custom solutions tailored to your needs.

Our company has developed a "Step Sensor" suitable for gradually sensing arbitrary load changes of liquid volumes and various objects. We can accommodate prototyping to mass production according to your application and purpose, including the number of steps (stages) of the load you wish to detect, as well as your desired size, shape, performance, surface processing, and printed design. Devices for displaying output from the sensor and transmission systems (such as wireless transmission units) are available upon separate consultation. 【Features】 - Ultra-thin sensor (approximately 3 to 5 millimeters depending on size) due to PET film laminated structure (resistance output) - Capable of detecting difficult-to-measure objects like sand, gravel, and rainwater in several stages - External dimensions and steps (number of load stages and load values) can be custom-developed according to customer requirements *For more details, please refer to the PDF document or feel free to contact us.

Isn't it true that even large-looking switches don't respond unless you press the center? The big switch responds to the entire surface! It's operable with work gloves or rubber gloves too.

We have developed the 'Deka! Switch', a membrane sheet switch series with an outer diameter of 45mm. It can be used in conjunction with standard membrane switches and features built-in LEDs for backlighting. We can accommodate your design requests from prototype to mass production according to your applications and purposes. It excels in heat resistance, waterproofing, and durability, making it suitable for applications that require environmental performance, operation with work gloves or rubber gloves, products for the elderly, sports equipment, and operations while in motion. 【Features】 - Sheet-type circuit and film laminated structure design - Ultra-thin, around 1mm - Tactile feel equivalent to a tactile switch with a click sensation - Built-in LEDs for backlighting - Dedicated push button unit can accommodate up to 45mm *For more details, please refer to the PDF document or feel free to contact us.

The dial has a rotation range of 270 degrees and up to 18 notches! The notches can be customized simply by changing the internal components.

Our company has developed an ultra-thin "Rotary Volume & Encoder" for sheet-type circuits and thin rotary mechanism design. It offers ultra-space-saving installation, just like mechanical types, by simply sticking it on (screwing is also possible). It can be used in conjunction with membrane switches, and we also provide a sheet type that can be used by touching with fingers. 【Features】 ■ Patented ■ Encoder: 360 degrees, 30 notch detection ■ Molded dial: The number of rotation notches is 18 or fewer, and the notch count can be changed simply by replacing internal components. ■ It is possible to mix sheet switches (membrane switches) with rotary volume/encoder on the same sheet. ■ If you wish to change the shape or size of the knob, we can accommodate that separately. *For more details, please refer to the PDF document or feel free to contact us.

From March 24 (Tuesday) to March 27 (Friday), 2026, RheaVita will exhibit as a conference sponsor at ISLFD, held in Fukuoka, in collaboration with Lifix Analytical. ISLFD is an international conference where researchers and engineers involved in freeze-drying and related technologies gather from around the world to exchange information and discuss research results and technological trends. Through our sponsorship at this conference, RheaVita will present the latest information on spin freeze-drying technology. At our booth, in addition to introducing the latest information about spin freeze-dryers, we will be open to consultations on a wide range of topics, including research and development, feasibility testing, scaling up, and comparisons with existing processes. We aim to create a valuable platform for information exchange for those asking questions such as "What is spin freeze-drying?", "What are the differences from conventional freeze-drying processes?", "What are the challenges of scaling up and reproducibility?", and "What new formulation and manufacturing approaches should be considered?". Additionally, individual meetings will be possible during the conference. If you contact us in advance, we will secure a meeting opportunity at a time that is convenient for you. Please be sure to stop by the RheaVita booth.
