Bring your biosensor into skin-worn research with replaceable sensor cards and a reusable holder.
Designed for research and development. Electrochemical readout is provided by the PalmSens Sensit Wearable. The research setups shown illustrate possible experiments.
FROM BENCH TO WEARABLE EXPERIMENT
A card-based system gives sensor developers a route into skin-worn, initially sweat-facing experiments. Iterate the chemistry or electrode design without rebuilding the entire wearable geometry.
The reusable holder connects the Sensor Card with the measurement setup and the skin-contact layer. The Underlay Patch is a replaceable, single-use component that transports sweat to the sensing area. It must be replaced before each new participant test, while the holder remains in use.
An SD-card-style insertion mechanism supports changing the sensing card. It is not a standard digital memory card.
THE COMPLETE SETUP
01
A reusable structure for the skin-worn test geometry.
02
An exchangeable card carrying the electrodes or sensors under investigation.
03
A replaceable skin-contact layer for the wearable experiment.
04
The electrochemical evaluation module. Measurement hardware supplied by PalmSens.
SENSOR INTEGRATION
Integrate a suitable biosensor on a Sensor Card, insert it into the Holder and evaluate its response in a wearable geometry.
The electrode layout and sensing chemistry define which marker the experiment can investigate.
An absorber layer supports sample collection and delivery within the sweat-facing geometry.
The cover and inlet form the interface for the intended sample path. The arrangement is matched to the study.
TWO WORKING ELECTRODES
The PalmSens Sensit Wearable uses two working electrodes with a shared reference and counter electrode. In Bipotentiostat mode, suitable techniques such as chronoamperometry can record both working electrodes simultaneously.
Glucose and lactate are example research targets for suitable sensing chemistries. The actual analytes, card configuration and protocol are agreed for the project.
Parallel Bipotentiostat operation is technique-dependent. It does not apply to OCP or EIS.
SENSOR CARD OPTIONS
BLANK
Blank Sensor Cards for integration of your own sensor concept, subject to technical compatibility.
GOLD ELECTRODES
Sensor Cards with gold electrodes as a starting point for suitable experimental designs.
PREDEFINED SENSORS
Cards with predefined sensors can be discussed according to the project and availability.
MEASUREMENT & CONNECTIVITY
Change the sensing card as your experiment evolves. Use the supported PalmSens PC or Android software to configure a suitable measurement and review the resulting data.
01 / CONNECT
Use Bluetooth Low Energy or USB-C as supported by the measurement setup and software.
02 / CONFIGURE
Set parameters for a supported technique, such as OCP, cyclic voltammetry or chronoamperometry. Available combinations depend on the mode.
03 / EXPLORE
Inspect measurement plots and export data for further analysis using the supported software.

FROM SENSOR PERFORMANCE TO WEARABLE EVIDENCE
A promising signal on the bench is a starting point. A wearable study also has to consider sample access, the electrode interface, mechanical contact, motion, temperature and the measurement protocol.
01 / SENSOR
Define the target marker, chemistry, calibration approach and expected interferences.
02 / SYSTEM
Review how the Sensor Card, Holder, Underlay Patch and electrochemical readout work together in the planned setup.
03 / WEAR
Evaluate the signal alongside contact, comfort and sample availability, then use the findings to guide the next sensor iteration.
