From complex microstructures
to reliable data of your products
Typical use cases: the measurement problem, our direct microforce-based approach, and the data you end up with.
Two-photon polymerization (2PP) microstructures
Problem
Microstructures printed by two-photon polymerization (2PP) are often too small, too soft, too fragile or geometrically too specific for conventional mechanical characterization tools.
SensiTips approach
Microforce sensors with adapted stiffness and a contact strategy defined for your geometry generate reliable force-displacement data on microbeams, micropillars and similar microstructures.
Measured outputs
- Stiffness
- Young's modulus
- Viscoelastic behavior
- Repeatability across structures
- Comparison between fabrication parameters
Value
Researchers obtain data suitable for publications. R&D teams obtain quantitative mechanical feedback that reduces trial-and-error loops during microstructure development.
Microbeams and micropillars
Problem
Bending an isolated microbeam or compressing a micropillar requires applying the force at the right point, along the right axis, without damaging the structure — something standard instruments rarely allow.
SensiTips approach
The sensor, its tip and its loading axis are chosen to match the structure's geometry. Bending and compression tests produce force-displacement curves directly linked to the structure's mechanical model.
Measured outputs
- Bending or compression stiffness
- Modulus extracted from the geometric model
- Behavior up to high forces when needed
Value
Data that validates — or invalidates — a design or a numerical model before committing to the next development step (R&D) or quality control (production).
Soft micro-objects
Problem
Hydrogels, elastomers, soft polymer structures: very low stiffnesses demand tiny measurement forces — otherwise you crush the object instead of characterizing it.
SensiTips approach
Low-stiffness sensors (from 1 N/m) with nanonewton resolution apply controlled loads matched to the object's softness, in quasi-static as well as cyclic testing.
Measured outputs
- Stiffness and apparent modulus
- Viscoelastic behavior (creep, relaxation, hysteresis)
- Repeatability across samples
Value
Quantified mechanical properties on materials that classical nanoindentation struggles to characterize.
Micro-actuators
Problem
How much force does your MEMS or actuator really generate? Models give an estimate — experimental validation requires a direct force measurement, at the right contact point.
SensiTips approach
The sensor is positioned in contact with the actuator and measures the generated force as a function of command, displacement and time.
Measured outputs
- Generated force vs command
- Actuator force-displacement characteristic
- Gap between model and measurement
Value
Experimental validation that consolidates the model and de-risks the next design iterations.
Process validation, quality control and advanced materials
Problem
A change of process, in your tests or in production, alters the mechanical properties — but by how much? Without measurement, development proceeds blindly or your production can diverge.
SensiTips approach
Comparative measurement campaigns, with a constant protocol, quantify the effect of each process parameter on stiffness, modulus or viscoelastic behavior.
Measured outputs
- Quantitative comparison between parameters
- Process repeatability indicators
- Process → mechanical-properties mapping
Value
Less trial-and-error, data-driven process choices, and a solid technical file for your customers or reviewers.
