Force sensors: challenges in wet environments

Force sensors have problems in wet places. Water, humidity, and electrical noise can hurt how sensors work. Engineers need to know these dangers to pick the best sensor for each job.
Water ingress
Water ingress happens when moisture gets inside the sensor. This can happen to force sensors, strain sensors, and fluidic soft sensors.
Component effects
- Water can rust inside parts, which makes them break and stop working.
- Moisture can cause short circuits, which mess up the signals sensors need.
- Some sensors, like piezoresistive sensors, last longer in humid air. Capacitive sensors can handle pressure for a short time but still have trouble with water.
Corrosion risks
- Rust makes sensor parts and connections weaker.
- Over time, rust can break sensors and make them fail.
- High humidity makes rust more likely, especially in sensors with metal showing.
Electrical issues
Wet places cause many electrical problems for force sensors. These problems can make sensors wrong or stop working.
Short circuits
Issue | Description |
---|---|
Moisture ingress | Makes rust and shorts, which cause wrong readings or total failure. |
Connector and cable failure | Wet air can break connectors and cables, hurting sensor work. |
Electrical noise | Can mess up signals, so measurements are not reliable. |
- Wetness for a long time can rust inside wires.
- Water can make paths that connect parts and cause shorts.
- Shorts often make sensors give wrong numbers or shut down.
Signal loss
High humidity can make water drops inside the sensor. These drops can short wires or rust parts. After a while, sensors work worse. Sensors may start to drift, so numbers are less true because of moisture. Water vapor can also add noise, making sensor data hard to read. These problems happen to force sensors, strain sensors, and other types.
Note: IP ratings help people pick sensors with the right protection. Higher IP ratings mean sensors are better at stopping water and dust. Picking sensors with good IP ratings lowers the chance of water getting in and causing problems.
Solutions for wet conditions
Protective coatings
Waterproof types
Engineers put special coatings on force sensors to keep out water. Parylene coatings make a tough shield against chemicals and germs. Makers use vapor to cover the whole sensor with this coating. Parylene C stops water and bad gases, so it works well in wet places. Antifouling coatings help marine sensors last longer by stopping things from sticking. Polyethylene glycol coatings make a layer that keeps away living things, so sensors last longer. SLIPS surfaces work well in still water and help sensors stay clean.
Sealing methods
Sealing keeps water from getting into sensors. Makers use gaskets, O-rings, and glue seals to close up sensor cases. These seals block water from touching important parts. Engineers test seals with pressure and water to make sure they work. Good sealing helps strain sensors and fluidic soft sensors stay correct in wet places.
Materials and enclosures
Non-corrosive options
Sensor cases protect inside parts from water and rust. Stainless steel does not rust and is good for factories and hospitals. Aluminum is strong and light, so it is used in cars and gadgets. Plastics like PEEK, PVC, and nylon do not react with chemicals and cost less. Brass is easy to shape and carries electricity well for pipes and air systems. Titanium is strong and does not rust, so it is used in the sea and in medicine.
Material | Key Properties | Applications |
---|---|---|
Stainless Steel | High strength, corrosion resistance | Industrial, food and beverage, medical |
Aluminum | Lightweight, thermal conductivity | Automotive, aerospace, consumer electronics |
Plastics | Chemical resistance, lightweight, cost-effective | Automotive, industrial, consumer electronics |
Brass | Corrosion resistance, machinability | Plumbing, HVAC systems |
Titanium | Strength-to-weight ratio, corrosion resistance | Marine, medical, aerospace |
IP ratings
IP ratings show how well sensors block water and dust. Higher numbers mean better protection. IP68 sensors can stay underwater for a long time and not break. Engineers pick sensors with high IP ratings for wet and rough places. This helps force sensors and strain sensors work well where there is water and damp air.
Sensor design

Submersion adaptations
Sensor changes help them work underwater. Multi-directional force sensors have waterproof parts to get IP68 ratings. These sensors still work after being underwater for days. Engineers test sensors at different depths to make sure they are stable. Good design keeps water out and lets sensors work in water jobs.
SOUSHINE’s Force Sensing Resistors use a bendy base and special material. This design helps them work in wet places and underwater. SOUSHINE makes FSRs in many shapes and sizes for different wet uses.
Humidity resilience
Sensors have problems in humid air. Superhydrophobic sensors stop water from sticking and keep working well. Materials like MXene-sodium alginate sponges make a wall that blocks water vapor. These things help strain sensors work in very damp air. Water can cause drops and ice, which can hurt sensors. Engineers pick materials and designs that fight humidity and keep sensors working right.
Tip: Picking sensors with waterproof coatings, strong seals, and cases that do not rust helps them last longer in wet places.
Force sensors: applications
Medical devices
Monitoring
Medical devices use force sensors to watch things closely in wet places. These sensors check fluid levels in pumps and dialysis machines. They also help doctors during surgery by giving quick feedback. In physical therapy, strain sensors measure how hard patients push. Orthopedic devices use force sensors to check pressure on joints and bones. MRI machines use sensors to watch patient movement.
Application Type | Description | Water Resistance Requirement |

These jobs need sensors that can handle water and cleaning. Flexible designs make it easy to fit sensors in different devices. Custom sensors help meet special water resistance needs.
Sterilization
Sterilization is very important in hospitals. Devices often get hot or face strong chemicals. Some ways to clean, like autoclaving, can make materials crack or lose stretch. This can make strain sensors not last as long. Other ways, like ethylene oxide or low-pressure gas plasma, are gentler on sensor materials. Picking the right cleaning method helps sensors work well and last longer.
Industrial automation
Food processing
Food factories use force sensors in wet and washdown areas. These sensors must handle lots of cleaning with water and chemicals. Most places pick sensors with IP67, IP68, or IP69K ratings. IP67 sensors keep out dust and short water dips. IP68 sensors work underwater for a long time. IP69K sensors can take strong, hot water sprays.
- Food sensors often use stainless steel to last longer.
- Sealed sensors stop water from getting inside.
- Conveyors and mixers use these sensors to measure force exactly.
Chemical environments
Factories with chemicals need sensors that do not rust. Stainless steel and special plastics protect sensors from harsh stuff. These materials help sensors keep working after many cleanings. Strain sensors in these places must give true data and last through lots of cleaning.
Marine and outdoor
Navigation
Marine places have special problems. Saltwater makes things rust, and sensors must work at different depths. Navigation systems use sensors that do not rust and can handle pressure changes. These sensors help guide ships and watch equipment on board.
Challenge | Description |
---|---|
Corrosion | Sensors must not rust in saltwater. |
Pressure at Various Depths | Sensors need to work under changing water pressure. |
Harsh Conditions | Sensors must survive tough weather and marine places. |
Reliable Communication Systems | Sensors must send data in hard conditions. |
Leak detection
Outdoor and marine systems use sensors to find leaks in pipes and tanks. These sensors must work in wet, salty, or damp places. Good leak detection keeps equipment safe and stops harm to nature. Force sensors and strain sensors both help in these safety systems.
Tip: Picking the best sensor material and protection helps sensors last longer in wet and tough places.
